Olga Michai picture

Olga Michai

Head of Customer success department

Olga is one of our most prolific globetrotters and is the only team member to have met everyone at S&F in real life. She has a masters in biology and experience as a lecturer and academic advisor in forestry and horticulture. Olga’s love of science fiction and desire to be at the leading edge of things brought her to the tech industry, where she joined us initially as an intern. She quickly progressed to becoming a project manager and then almost single-handedly built up our Account Management Department from scratch. She now leads the customer success department and is passionate about the personal and professional development each new role and project offers.
In early 2020, Olga completed the three-day Developmental Sprint Leader Training with Bob Kegan, which gave her further tools to tackle the inevitable challenges of working in software development as growth opportunities in disguise. Read More >> She’s excited about the ongoing learning curve that being part of a DDO provides. Olga’s story with S&F is a living testimony to what she considers to be our core strengths – the meritocratic approach, the wide range of opportunities for growth, flexibility, and the great team spirit. Her life goals include seeing the nearby planets, achieving some great things for her descendants, and retiring to a tropical island. << Show Less

Head of Delivery

Navi Tulkun picture

Navi Tulkun

Producers lead

Navi’s aspiration is to build a perfect project management process, where everyone is as effective as they can be, and the best possible value is delivered to the clients. With that goal as her guidance, she monitors our working processes to identify and address any weaknesses and risks, helps producers solve emerging problems and adopt more effective methods of project management, and generally does everything possible for our clients’ projects to be successful.
Having found her previous job in a startup constraining, Navi joined S&F for an opportunity to apply her knowledge and skills more broadly by implementing different scale projects in a more diverse team. The absence of unreasonable bureaucracy and the openness to creative solutions were her other pleasant discoveries at our company. A great believer in tech innovations as a perfect tool to create a variety of things that can be useful to many, Navi already has an experience of developing her own product (a gamified service for investment in farming, which has helped increase the availability of quality local produce), and one day hopes to spearhead a ‘unicorn.’
Read More >> Navi admits to being practically haunted by her goals and ideas, and her ambitiousness manifests itself in all aspects of her life. (Even in sport, Navi could not be satisfied by just taking a class or two and went on to become a sambo champion of her hometown!) Her inspiration often comes from movies based on real-life stories, particularly those about people who achieved incredible success thanks to their hard work and tenacity, the two qualities she has in abundance. When Navi needs a break from conquering the world, she watches freestyle wrestling, goes horse-riding, plays ping-pong, and researches beagle puppies. Getting one has been her dream since her time in London, which also gave her English a distinctly British flavor. Born in Uzbekistan, Navi comes from a diverse background of Central Asian ancestry and speaks seven languages, including three dialects of Ossetian. << Show Less

Anri Bolon picture

Anri Bolon

Lead Engineer/Solution Engineer

Anri grew up in a family of mathematicians and followed the lead of his older brother in familiarizing himself with computers and programming from an early age. Even though he now says that his origins left him no choice but to become a software engineer, before moving into tech, he first got a master’s degree in economics. That came in handy later when Anri worked on e-commerce projects as a lead web developer with a digital marketing agency, prior to joining S&F as an Engineering Lead.
Now, after more than seven years with us, Anri describes himself as “the shepherd and the priest” for our software developers in their mission to convert our clients’ needs into solid products. He is, in turn, much valued by the team for his proficiency in everything JavaScript, approachability, patience, reliability, and his inquiring mind.
Read More >> Anri is exceedingly modest and does not like the concept of being “proud” of anything. He does admit though to a superb collection of funny stories, sufficient for a good book (we add, much anticipated if he ever decides to go ahead with it!). For now, it, however, remains a project of the distant future, while Anri is busy traveling and hiking with his wife, being an avid music fan, playing guitar, and watching his favorite TV shows. << Show Less

Aside from coding, Ivan is actively interested in discovering new methods of spam detection as well as the science and engineering of making intelligent machines. In his free time, Ivan enjoys science fiction novels and online role-playing games.

Lena Pallna picture

Lena Pallna

Producer, Business Analyst, QA Engineer

With over seven years in project management and over five in QA, Lena draws inspiration for her multiple roles with S&F from the sense of joy shared by the client and the team at the end a good project. She equally relishes finding glitches and solutions, as both require getting to the core of the matter fast, something that Lena is immensely good at, not least thanks to her propensity to ask questions when something is unclear, without fear of ever appearing incompetent. She likes to see projects all the way through to completion and is incredibly persistent, if not particularly patient. (In fact, she hates waiting so much that she would rather show up slightly late for meetings just to avoid it!)
At S&F, Lena appreciates the close-knit team, the opportunity to interact with people of different nationalities and to keep pace with the tech progress, along with regular access to training which helps her stay on top of her profession.
Lena’s personal aspiration is to lead a life without regret. Well on track to this simple yet stimulating objective, she is proud of her nine-year-old daughter, her master’s degree in mathematics, her driving and foreign language skills, and her independence attained through hard work.
Lena loves traveling with her family (albeit always leaving one of its members, Murka the Cat, behind), playing board games with friends, and engaging in sports that value speed, like roller-skating, skiing and snowboarding. The only thing she currently wishes for is more time for her newest adrenalin fix – reading adventure novels.

Max Tor picture

Max Tor

UI Engineer

Max’s goal is to develop in many different spheres, both professionally and personally, and he does not waste time pursuing it. Within the past ten years, he has ventured into a variety of web development and e-commerce directions, and now holds certificates in web design, e-commerce, database development, and web layout, on top of his degrees in engineering, applied science, and management. With S&F, Max is currently focusing on User Interface engineering, with an eye towards taking responsibility for entire projects (and their teams) sometime in the near future. Outside of the office, he has dabbled in snowboarding, kitesurfing, paragliding, surfing and photography, among other things, while constantly trying something new.
Read More >> Despite his hankering for novelty, Max is endearingly pedantic in his daily habits. He wakes up with the sun and takes his Scotch terrier for a walk. Once he gets to the office, he makes sure that none of the windows are draped and that there is as much light in the room as there can be. Then he brews himself a cup of tea, the first of about twenty he drinks while working (or of about a hundred if he is having a stressful day). He is very precise in how his desk should be organized and knows immediately if anyone has touched it. Max’s favorite aspects of his work are socializing with clients and colleagues and finding optimal solutions to people’s needs and problems. Together with his adventurous and punctilious nature, his well-developed communication skills make him particularly good at it. << Show Less

Peter Sirotinsky picture

Peter Sirotinsky

Mobile and CMS Engineer

Peter is our Renaissance man. He describes himself as modest, smart, practically an Apollo, and a rare workhorse (“well, someone has to be, right?”). With such a starter kit of personal traits, he believes that his key achievements are still ahead of him, although seven years of software engineering experience, a degree in computer science, and participation in some of our most unusual projects are definitely something to be proud of.
Currently, Peter is working as web, mobile (native iOS and hybrid), and JavaScript developer, as well as a CMS engineer. He views his job almost as a drug and has found S&F to be a reliable supplier of his daily dose of challenge, in an environment optimally combining flexibility and professionalism which is not synonymous with tediousness.
Peter’s versatile talents are not limited to tech and encompass, among other, Irish dance, playing keyboard, and sketching. He also has a deep interest in folk and rock cultures, reads a lot, and enjoys cinema and hiking.

Sasha Hariton picture

Sasha Hariton

Software Engineering Lead

Web development is not a job but a passion for Sasha, and he often laments having to spend a good chunk of his time on other things, like project launch and control. That, however, has helped him reach a level of expertise in a variety of areas of S&F’s work where he can now address any issue for our clients, except contracts and invoices, something he is actually quite proud of. His primary focus, nevertheless, has been Ruby on Rails and content management systems.
Sasha has discovered his path to glory in taking over, persevering through, and succeeding in tasks that appear too confusing or insurmountable to others. He likes to treat our clients as partners in projects and counts his communication skills, along with the weight of his word in the team, among his key strengths.
Read More >> Sasha’s personal goal is to find his own way in life and to consistently be able to take care of his loved ones (as well as to eventually learn to show up to offline meetings on time). He adores his wife and their teacup yorkie. A warrior at heart, he enjoys soccer, which he has played since an early age, and mixed martial arts, his newest hobby. << Show Less

Vas Jaremchuk picture

Vas Jaremchuk

CMS Practice Lead

With 15+ years of Drupal experience, Vas initially started with S&F a few years ago as a sub-contracted freelancer and later assumed a permanent team role. He now helps the company to minimize custom development by looking for existing solutions to emerging needs. He especially likes addressing new challenges to which he does not have an immediate answer.
Vas is inspired by the idea that he may one day create a product that would attract customers directly through its webpage or a GitHub, without the need to proactively and continuously sell it. His long-term dream is starting his own business with headquarters in New York City!
Vas studied in Moscow and got a PhD in Fluid Dynamics. In 2007, much to his friends’ consternation, he moved to Kyiv - and has not regretted that decision for a day. He appreciates the more relaxed pace of life and the opportunity to often work from home, dedicates to his wife Irina and two daughters, Sofia and Margarita, the hours he would otherwise spend commuting. Read More >> Vas is very protective of his family’s privacy and possessions. That is particularly manifested in his habit of pulling heavily on the door handle of his 25th-floor apartment every time he goes outside, to be absolutely certain that the door is locked. (He admits to breaking quite a few doors handles that way!) << Show Less

Tim has been working for Speed & Function since 2011. He is a charismatic individual with a unique sense of humor and is appreciated by both the team and our clients. Tim graduated with a degree in computer science and networking. This was a clear choice for him, since technology has been his passion from a young age. Tim started experimenting with coding in middle school and began coding professionally when a friend invited him to help out on a project in 2007. Tim excels at UI engineering and Node.js and plans to build more iOS apps in the near future. In addition to software engineering, Tim is interested in radio electronics.

Alister Ignatius picture

Alister Ignatius

Developer (FE, BE), Solutions Engineer

Alister graduated from the National Aerospace University in 2015 with a degree in system analysis. He focused on mathematics and data processing in his studies, and it was there that he started programming in C# and C++. Alister later returned to his alma mater to run a computer science lab. Having joined S&F as an intern, he quickly rose to become a solutions engineer specialized in JavaScript, thanks to his ambition, hard work, and conviction that he could succeed in anything he would put his mind to.
Alister considers software tech to be the future and looks down upon most other occupations as “the past”. Despite that, like many of us, he sometimes feels the need to escape to tech-less worlds, giving strong preference to Middle Earth of the Lord of the Rings film series and 19th century France of the Count of Monte-Cristo, one of his favorite novels.

Vadim Jin picture

Vadim Jin

Software Engineer

Vadim began his career as a system administrator, but later found a better application for his degree in mathematics and computer science in Drupal development. He joined S&F in 2016, after only three years in the field, and is now well on track to becoming a leading developer.
Tenacious and persistent, Vadim is so strongly oriented towards self-improvement that, when asked about his achievements, he would never give a straight answer. Each conquered height for him is just a springboard to see a new horizon, set a new goal, and keep moving forward.
As someone ever worried about forgetting to lock his apartment or car door, Vadim considers surrounding himself with those he can trust a key to happiness: his wife, daughter, cat, and his team at S&F are counted among the privileged.
In his free time, Vadim practices the art of ambrotype photography, finding inspiration for his work everywhere, from his family, the streets of his hometown, and simple everyday objects, to arthouse and world cinema classics like The Elephant Man or The Godfather. He also enjoys sports; snowboarding is his favorite.

Ellen Svejin picture

Ellen Svejin

QA Engineer

While studying psychology in college, Ellen took an opportunity to do a QA engineering internship with a startup and was inspired to try a variety of software development roles, including project management. She went on to lead a number of projects from inception to finish, mastering myriad tech skills along the way. Not surprisingly, when a friend introduced Ellen to S&F, she felt like it was a match made in heaven. Open-minded, extraverted, flexible, and self-motivated, she found a perfect environment to set free her infinite curiosity and realize her versatile potential.
Outside of work, Ellen maintains a strong interest in her original field of studies and reads extensively on psychology, medicine, and nutrition. These come in particularly handy now, as she and her husband recently became parents for the first time.

Anna Bondar picture

Anna Bondar

QA Engineer

Anna grew up in a family of computer science teachers who cultivated her love for math and engineering since her early childhood. She graduated with a dual master’s degree in Computer Science and Management and dove right into quality assurance. After a decade in the profession, she firmly believes that a good QA Engineer does not have failed projects, only routine issues to deal with and, if treated with due care, can help shape results that go well beyond clients’ expectations. Anna’s own record of innumerable completed projects, quality products, and contented clients, is largely due to her ability to get fully immersed in her work, identify priorities, learn fast, and persevere in the face of challenges. She admits that none of her multiple certificates (ISTQB, QA automation, test management, and test analytics, to name a few), although a definite achievement, give her as much pride and satisfaction as a job well done. As one of our most experienced team members, she often takes a leading role and coaches younger colleagues, infusing them with her ceaseless excitement for new projects and ideas.
Easy-going and communicative, Anna finds joy in surrounding herself with good people and interesting events. She is proud of being a mother and a homeowner. Her free time is divided among drawing, dance, sports, hiking, reading, and watching fairy tale adaptations. With so much going on, one thing Anna never seems to find time for is getting a decent hairband: her long hair is often seen being precariously held together by a pen or a pencil. (Quite possibly, she just wants to be always prepared to sketch something – or to add another party to her diary.)

Inna Mis picture

Inna Mis

Producer, AGILE SCRUM Master

Inna has a bachelor’s degree in computer science and had worked as a UI Engineer before deciding to look for an occupation that would help her grow as an entrepreneur and a project manager. Her search led her in 2016 to Speed and Function’s team of producers where Inna finally got a chance to convert her creativity, positive mindset, and drive for quality, into an extensive portfolio of successful projects. Always in pursuit of a challenge, and detesting routine, Inna prides herself on having taken on (and won over) some of our most demanding clients.
Independent since an early age, and with a travel record of over 20 countries (including experience living in three of those), Inna is full of the most amusing and bizarre stories (none, however, are fit for print). Fearless as she may seem, Inna does admit to keeping her eyes half-closed when watching horror movies and occasionally hiding behind her cat Simba if the action on-screen becomes too frightening.

David Sonne

Product Owner

David studied computer science and mathematics in college, then moved to Himalayan China as a missionary for 10 years. During that time he got an MBA in international economic development, and became involved in funding development projects. He traveled all over China, and spent a lot of time in villages, farms, factories, and government offices, getting to know the local people, NGOs, and how things work in China. He later founded a consulting company and started funding and running development projects directly, the major focus being water projects, animal husbandry, and scholarships. He also founded an agricultural development company, and started three farms, growing a near-extinct kind of herb organically. He moved back to the US in 2010 for some real estate investments, building two 3-story houses by hand, which are now providing rental income. During his time in Philadelphia, he started a permaculture fruit-forest covering several vacant lots. He is block captain, and also head of the Tree Tenders for North Philadelphia. In his spare time, he started building a 3D parallel-dimension turn-based strategy war game from scratch, and soon started using games to teach programming.

Alex Ost picture

Alex Ost

Drupal Engineer

Alex was working on a PhD in genetics and teaching college-level anatomy classes, supporting his studies through a job at a maritime agency, when he realized that he was actually an artist. Not the Van Gogh type, for he wanted to create something beautiful and useful, preferably without any risk to his bodily integrity. Alex found his calling in software engineering and Ruby on Rails, and is currently focusing on the back end, with an eye towards becoming an indispensable Fullstack CMS developer.
Alex is valued in the S&F team for his lack of preconception and prejudice, high trainability, and attention to detail. He charms our clients with the way he cares about how the projects he contributes to will turn out, as well as with his surprisingly minute reports.
Unlike many others, Alex is impatient to turn 45, the blissful moment when he releases his kids into the world. While he considers them his main source of pride and motivation, he does look forward to the time when he can finally enjoy all his favorite animated features, especially Japanese anime, in uninterrupted peace and quiet.

Helen Klymenko picture

Helen Klymenko


If Helen was Wonder Woman trying to go incognito in the “real” world, we’d say she wasn’t doing a very good job hiding her superpowers. A PhD in cellular biology and a bodybuilder of four years, Helen has years of project management experience and joined S&F with aspirations to become a Digital Producer. (Even if she later loses interest in this career path, her impressive skills in plucking and carving poultry have her covered!) Invaluable for her love of paperwork and keeping things organized, Helen drafts contracts, keeps an eye on timesheets, talks to clients, coordinates the team and monitors project performance. She believes that her persistence, attention to detail, constant pursuit of improvement, and ability to acknowledge mistakes and learn from them are her keys to success. We believe it’s her big heart (Helen modestly considers helping her sister conquer cancer her biggest achievement. She also once rescued a cat, but that’s just a regular day for a superhero, isn’t it?).
Motivated by the prospect of a tasty breakfast followed by at least three cups of Americano, Helen wakes up early even on weekends and looks forward to learning something new every day.

She likes to read popular science books on physics and biology and moonlights as a freelance translator of patent applications from English into Russian and Ukrainian. Her non-scientific interests include watching crime shows, medical dramas, or thrillers while sipping on one of her favorite drinks (whiskey or Jägermeister), and spending time with her family (mom, brother, and sister) or boyfriend (not necessarily in that order). << Show Less

Helga Nikitin picture

Helga Nikitin

Account manager

Helga contributes to S&F’s projects by monitoring budgets, timelines, and resources, as well as assessing and addressing present and emerging risks. Coming from an educational background, Helga treasures her time with S&F (five years and counting) for the progress that she has made towards her professional development goal of becoming a recognized expert in product management – as well as towards her personal goal of making the world a better place. She also highly values the S&F team, flexible hours, and access to opportunities for growth through the regular training that the company offers.
Independent since the age of 17, Helga has moved cities (and countries!) on her own and prides herself on her perseverance, communication skills, and ability to see hidden challenges. She is motivated by her keen interest in people and in learning something new every day. Helga loves solving riddles and once spent a day going through three escape rooms! She also likes horror films and theater, the latter having been her hobby some years ago. (Interestingly, Helga remembers always being cast as evil characters – a great contrast to her personality and mission in life!).

Oxana Bagro picture

Oxana Bagro

HR Manager and Recruiter

Oxana’s over ten years in HR, recruitment, staff development, and training are distilled in her simple and elegant professional motto: “No people – no profits.” Indeed, none of S&F’s projects would be possible without the best people, whom Oxana supplies with a sense of purpose, efficiency, concentration – and a pinch of salt. Proud to be a United Nations Development Programme-certified soft skills development trainer, Oxana loves communicating with people and helping them grow professionally and personally. At S&F, she is particularly inspired by the unusual tasks and situations which abound in hiring, onboarding, adaptation, and training of our team. (Once Oxana, through a humorous misunderstanding, ended up being interviewed by a candidate for an HR position with us, which she immediately used as an opportunity to assess the candidate’s skills in action!)
Oxana’s personal goal is to be happy and enjoy life as much as possible. Read More >> Her husband, two sons, cat, and turtle are very much on board with that. Oxana, however, does not limit herself to a quiet family existence. Her adrenaline fixes come among others from reading and watching thrillers and crime stories, as well as from scuba-diving. (To illustrate how nerve-wracking the latter can be, Oxana recalls trying to take an impressive closeup photo of a moray eel and ending up having to run – or rather, swim - for her life.) << Show Less

Stephan Protsack picture

Stephan Protsack

Full Stack Developer

Stephan is happy to wake up every day to the prospect of doing what he loves. (This includes about a hundred things – from writing code to creating estimates, assisting the sales team, and everything else, both at the front-end and server-side!) Goal-oriented, persistent, and curious, Stephan prides himself on his multifaceted skill set and ability to make quick decisions. He appreciates the opportunity to take up challenging tasks in a team of interesting individuals, which he has found at S&F.
Stephan describes his personal goal simply - “to see the world”. We suspect he wants to do that as a touring rock star, knowing that he plays guitar and is learning to play piano, or, as an amateur detective investigating macabre mysteries – considering his love of crime novels, especially those of Edgar Allan Poe.

Anatoly Shipitz picture

Anatoly Shipitz

Full Stack Software Engineer

When Anatoly transitioned from freelancing to a permanent staff role with S&F, he brought with him over 20 years of web development experience, to build software applications guided by his strong vision of a quality final result.
Anatoliy likes to feel useful and in-demand and enjoys the opportunity to work with cutting-edge technology in a supportive team while dealing with something new and unexpected every day. That is not, however, why Anatoly wakes up early every morning; like many parents of young children, he has to go through a considerable ‘to-do’ list to get his two kids ready for school before he can dive into coding.
Persistent and meticulous, Anatoly can figure out anything that interests him, even if it is completely unrelated to his profession. Read More >> Almost anything, that is – as long as he knows where he’s going with his research. (In one instance, just like Jules Verne’s Jacque Paganel, Anatoliy learned how to say a few phrases in perfect Portuguese, where what he actually needed was Spanish!). << Show Less

Vicky Sulzhenko picture

Vicky Sulzhenko

Account manager

Vicky left a managerial position in advertising to start a career as a business analyst and project manager in custom software from scratch. Goal-oriented, open to new tasks and challenges, meticulous, and attentive to detail, her personality is the right combination of ingredients to succeed in her professional and personal endeavors. Working as a Producer and Account Manager, Vicky keeps our clients abreast of the current status of their projects, informs them of emerging hurdles, offers potential solutions, and monitors budgets. She believes that the complexity of her work at S&F is exactly the learning platform she needs to implement the myriad grandiose plans she has built for her future, inspired by the success stories and biographies of famous people.
Read More >> Vicky loves to cook, particularly desserts, which she rarely eats, giving preference to savory foods. Most of her creations are consumed by her lucky husband. Fortunately for his long-term health, Vicky dislikes driving and insists that they ditch the car and walk to most places. She also occasionally taps into her ten-year experience of ballroom dancing to let loose. Vicky’s personal goal is “to seek harmony in everything,” which is essential to running her contemporary Noah’s Ark of a household. She and her husband take care of three cats, four pit bulls, a dachshund, and a parrot living under the same roof. In fact, Vicky could easily give Noah a run for his money, considering that she also manages her pets’ careers: her Maine Coon named Ashley has a large following on Instagram, and the five dogs regularly tour to participate in dog shows. << Show Less

Paul Petrovich picture

Paul Petrovich

QA Engineer

Paul is a versatile professional who can take on a variety of roles, including those of a tester, a lead, or a QA, drawing from his broad scope of experience with leading the US- and EU-based companies. His current focus is on enhancing the testing processes and products as a whole from the consumer’s point of view, adopting an approach which Paul himself describes as “pedantic” and “quality manic”.
Having chosen S&F for the opportunity to work remotely, Paul is highly valued for his confidence, strong understanding of business and product development, and the ability to effectively communicate with anyone.
Paul loves the routine and simplicity of home life with his wife and three-year-old daughter and works continuously on improving its quality, too. His free time is dedicated to professional photography.

Anastasia Gabriel picture

Anastasia Gabriel

Communication manager

Anastasia sees her mission in life as ‘living happily and helping others do the same.’ That is why when S&F was looking for someone who could create and nurture a welcoming, warm, and comfortable working environment at our office, we struck gold when we found her. Kind, empathetic, optimistic, and creative, Anastasia loves people and has an uncommonly high level of emotional intelligence. In addition to taking care of all kinds of household matters at our office, Anastasia plays an important role in HR management by helping onboard new staff, facilitating internal communications, and organizing corporate events, trainings, team building activities, and birthday celebrations. She also helps our overseas staff develop their English language skills and arranges tutoring, speaking clubs, and testing support.
Read More >> Anastasia values the atmosphere at S&F where everyone can express their opinions freely and be heard, and draws her inspiration to grow from working with the team of bright individuals. It is easy to see how neither would have been there without Anastasia. A win-win! (Incidentally, it is one of the principles promoted by her favorite book – Stephen Covey’s “7 Habits of Highly-Effective People”). True to the first part of her mission, Anastasia does not spend all of her time being a “mom” to everyone at S&F. Some of the things that make her life a happy one are raising her young daughter, taking fitness classes, and studying psychology. << Show Less

Alexander Laurie picture

Alexander Laurie

Software Engineer

Alexander works on the front end (typesetting and coding in ReactJS) helping our clients turn a picture into a web-app, a website, or a prototype. He has a master’s degree in information systems and management and previously worked as a user interface developer with Yandex.

On weekends, Alexander likes to go for car rides with his wife and, when he has more time on his hands, to play video games, his Bengal cat at his side.

Serge Shevchyck picture

Serge Shevchyck

Drupal Engineer

Serge was recently headhunted via LinkedIn as a solid and highly experienced Drupal developer. He now works with us on the back end, creating new features and maintaining old projects. At S&F, Serge values the good team and the opportunity to learn something from each new project. Patient and persevering, he chose the tech profession for his love of creating and maintaining things that make someone’s life better.
Serge’s personal goal is to travel more. For now, he is paving the path to his dream by watching thematic TV shows and following travel video bloggers.

Kristina Bazay picture

Kristina Bazay

FE Developer

Much like her favorite book character, George Sand’s Consuelo, Kristina is a self-made woman. She has a master’s degree in computer graphics and web design and is proud of having been accepted to university solely on the merit of her portfolio. Before recently joining S&F, Kristina worked on web development and tech solutions for music education, with a strong emphasis on graphic design, interactive features, and animation. In the meantime, she learned English by watching TV shows and YouTube videos, while also developing a keen interest in languages less widely spoken (her most recent fascination is Irish).
Kristina likes myths and adventure in all shapes and forms, especially if they are a product of the Marvel Cinematic Universe. When not immersed in the latest Avengers installment, she enjoys alternative rock, watches TV shows (her favorites include The Office, Parks and Recreation, Doctor Who, and Breaking Bad), and cheers for ManU.

Eli Gogha picture

Eli Gogha

MeteorJS and FE Drupal/ WordPress Developer

If Eli had not chosen a tech profession, he would have made a perfect firefighter. Honest and responsible, he is always prepared to do what’s needed, to quickly learn any skill required for that, and to be available online for the company and the clients to help, well, put down virtual fires. He is also a capable leader having headed teams of up to 13 people, trained and inducted beginners, and managed projects inspired by his own ideas and initiative.

Just like many firefighters, Eli has rescued lots of animals on his city’s streets and achieved impressive results in a variety of sports. Idleness is inconsistent with his personal goal of living a life he would not regret, so, when not coding, Eli keeps busy raising a daughter together with his wife, cycling, long-distance running, studying the history of East Asia, mastering computer games, and playing with his two pets, a dog and a cat. (Some of our clients have actually met the latter when during calls she coughed out fur balls under Eli’s desk so conspicuously, it simply could not be ignored, and she had to be introduced). Read More >> Subtlety is the only quality Eli has still to work on; although we do not necessarily look forward to the time our team conversations lose half their fun when he abandons his habit of driving them towards subjects not normally discussed in polite society. << Show Less

Serge Fomenko picture

Serge Fomenko

E-Commerce Solutions Specialist

It is hard not to think of Hercules casually going through his twelve labors to eventually ascend to Mt. Olympus and rest with the gods when enumerating all of Serge’s accomplishments. His engineering degree and consequent work in industrial manufacturing resulted in an invention patent. His comprehensive ten-year experience in sales and retail led him to become the COO of his company. He has, over the past five years, built an impressive digital portfolio of e-commerce projects, primarily as a Magento developer. And in the meantime, he got PMP- and SMSS-certified, with an eye towards taking over some strategic management tasks and ultimately growing into a CEO.
Going beyond professional exploits, Serge is a husband and a father. His hard rock band has been invited to play at two international music festivals. His basketball team is prominent in the local amateur basketball league. He has won a trail run competition in the 30-40 age category. He’s written a popular blog and moderated a forum on music. He has broken his collarbone mountain biking.
So what, after all, keeps Serge grounded? His open-mindedness. A cup of coffee. Good classical science fiction or psychology book. A forest, an ocean, or another similarly beautiful view outside his window. Some good old 80s and 90s film and music. On the whole, all that stuff that makes being only a demi-deity so worthwhile.

Dmitry Astapovich picture

Dmitry Astapovich

Web Developer

Dmitry works on website development and support. He loves his job in tech for its ever-expanding horizons and the constant inspiration to enhance his knowledge and skills, a perfect antidote to sloth and complacency. It is also a great outlet for his stubbornness, which, as it turns out, is incredibly useful when one has to deal on a daily basis with complex problems requiring detailed research and analysis.
Dmitry’s most immediate personal goal is to obtain a private pilot license. In between flight training and coding, he enjoys good coffee and films by some of the best directors of our time (his favorite so far is Stanley Kubrick’s Dr. Strangelove, or How I Learned to Stop Worrying and Love the Bomb).

Nazar Ilch picture

Nazar Ilch

Full Stack Developer (Ruby on Rails, Angular, React)

Nazar got a PhD in Materials Science from the Paul Scherrer Institute in Switzerland but later chose a career as a software developer instead. He saw tech as the sphere where he could get the most opportunities to create and grow continuously while working alongside some of the most interesting people of his generation.
Initially a freelancer, Nazar joined S&F on a few projects before being offered a permanent position. He readily accepted having found our team welcoming and supportive, and our working processes well organized. Nazar now develops products, provides estimates for project stages and tasks, and works directly with clients to demonstrate product features and address identified shortcomings. His current professional goal is to become an ultimate expert in his tech stack and a client relations guru while mastering other existing and emerging technologies and learning from others’ experiences of leading projects.
Read More >> At work, Nazar is happiest when he gets to analyze a particularly complicated problem and find durable solutions (preferably, while sitting at a window-side desk with a steaming cup of coffee). But whatever the task is, Nazar always strives to carry it out to the best possible level of completion (he even finds it hard to leave a book he does not enjoy unfinished!). He is valued for his strong drive for quality, his patience, persistence, and openness (particularly to feedback), and his integrity is almost legendary (Nazar once saved a client from being ripped off by a graphic designer who almost sold the latter a plagiarized logo!). Nazar is proud of his independence and motivated by anything which is a project of his own, be it his family, his work, or a personal endeavor. He loves sports and has played soccer and volleyball as part of amateur league teams both in Switzerland and back home. Great fans of the mountains, he and his wife always look for opportunities to go hiking in summer and skiing in winter. Indoors, Nazar’s free time is mostly dedicated to reading, which he has loved since being a child. His favorite book is The Master and Margarita by Mikhail Bulgakov, famous, among other things, for one of its characters being a mischievous talking cat. Perhaps that’s who Nazar thinks of when he often talks to his own cat Manu. Who knows, maybe one day Manu will answer back. << Show Less

Ally Pugolovok picture

Ally Pugolovok

Executive Assistant

With her two degrees in software engineering and banking, Alyona was headhunted for a position at S&F that combines all of her favorite things – tech, math, statistics, and English. She is now, among other, responsible for keeping our CRM up to date, tracking opportunities, making sure we provide all the necessary communications to our clients at the pre-sales stage, conducting research, and drafting reports, while also hoping to eventually dabble in data management and operations.
Alyona’s vision of the world as a place where animals thrive living alongside people starts in her own household. Her two cats are perpetually forgiven for waking her up early in the morning, get priority to be fed breakfast, and, unlike Alyona’s husband, are allowed on her work-related Skype calls (you may occasionally see them staring straight into the camera). They also share Alyona’s love of stretching exercises but are less supportive of her other pursuits such as reading and traveling.
