How we do it

We build custom software applications using today’s most advanced technology. But so do a lot of software engineering firms. So what makes us different?

Spark DSG

Spark DSG

Founded in 2011, Spark DGS is a design agency based in Doylestown, PA. S&F handles roughly 85% of Spark’s total development work. As the design agency continues to grow, its deliberately collaborative partnership with S&F only matures and expands in more mutually beneficial ways. When the COVID-19 pandemic hit, the two companies worked at an excruciating pace to successfully design and develop a site for a client, who makes ventilators, urgently needed during the crisis

SecureCore offers managers of multi-family properties (90% of their plans) customized, actionable emergency response plans. In 2017, SecureCore approached us to “rescue the project”  – the app that was crucial to interaction with their paid software. We helped them create a smooth and easy UX to let anybody at the property have access to the software. This way, each member of the organization embraces responsibility and has a solid understanding of the disaster plan: what to do in case of emergency and whom to call.

CertainTeed is North America’s leading brand of exterior and interior building products, known for innovation and sustainability. It’s owned by Saint Gobain, a 350 y.o. multinational corporation with $40b revenue and 180,000 employees. The company needed to build a website from scratch that would handle a multi-level catalog of products and lots of educational resources. 

S&F joined the development effort that was started by another agency and eventually took on full responsibilities of building a scalable website with easily editable design and powerful search and filtering options.

Large medical device company

Breathe easily: A ventilator manufacturer with offices in 100+ countries saw a massive spike in their product demand at the beginning of 2020 due to the COVID-19 outbreak. Neither their website, nor their mobile app were on-par with the customer demands. Localization was also an issue. That is why they called on S&F to help them create a better digital experience. Beginning with an audit, our team soon understood the main pain points that needed to be solved. In less than 3 months, S&F delivered an integrated, fast-working platform that responded to the urgency of the situation.
Tech and tools we used: Drupal, AWS, SASS, TWIG, jQuery, Jira.

A night at the online museum: The COVID-19 pandemic forced many institutions to expand on their digital presence. This was the case for the US-based museum that chose to partner up with S&F in 2021. They asked our team to set up an interactive website that would allow users to immerse themselves in their respective topic. In addition to the museum’s customer-oriented requests, S&F also worked on strengthening their protective measures and protocols for their new website, thus applying a preventive approach to cybersecurity.
Tech and tools we used: React Native + Drupal 8

Mind the crisis: A US-based engineering and consultancy business needed a custom-built web application to manage their hazard mitigation tasks. In their line of work, having the right digital space to help them streamline the complexity of handling crises is vital. The project demanded a high degree of technical sophistication, an assignment that was up S&F’s alley. In less than 8 months, our team built an environment that had all the required functionalities, underlining the usability and intuitive feel of the app interface.

Having had bad experiences with previous software development companies, they hoped S&F would be different. Starting from scratch, our team managed to cover the complexity of the firm’s processes through a custom-built environment that is fast-working and flexible. Our client appreciated the transparency and involvement we demonstrated in our collaboration.

Syneos Health

Syneos Health is a $4.6b multinational organization that helps companies with clinical trials and biopharmaceutical therapies. For the client that had developed four websites dedicated to Wilson’s disease and didn’t have quality assurance and quality control specialists, Syneos Health was looking for a professional QA team to test several websites under a tight deadline.

Cooperating with Speed and Function, Syneos Health set a deadline to cover the layout testing of 100+ pages across 4 browsers and 4 devices in a couple of weeks. The client did not have easy access to a QA team and all the testing work initially was done by managers. The S&F team had to find all bugs before websites’ production, ensuring their error-free release and seamless user experience in tight deadlines without documentations in suitable format at the start of the projects. Addressing immediate testing needs, QA engineers were also meant to build long-term support for these websites.

Top University-affiliated Network of Hospitals

Don’t skip a (heart) beat: A digital agency needed an extra hand with building a large marketing website for one of their clients, a top-university-affiliated network of hospitals. Next to the website refinements, the agency also wanted our team to use their SiteImprove scanning tool to record the platform performance. With all the changes applied to the website by S&F in only 1 month, our team bettered the site’s SiteImprove score, taking it from 52 to 67.4. A key part of our work was getting the entire platform to be ADA compliant, making sure the end-user navigates the space with ease.

This is what people think

Speed & Function has been an invaluable collaborator in expediting progress on the Wikimedia Foundation’s yearly engineering roadmap and key development projects. Whether it’s augmenting day to day maintenance of our platform codebase to more complex, strategic projects and experiments - we know we can trust Speed & Function to do the job well (and often ahead of schedule)
Mat Nadrofsky, Wikimedia Foundation
Director of Engineering
The S&F team has taken the time to develop a deep understanding of our program and how it works. They were very quick to pick up our Meteor.js code base and contribute to it productively. They are helping us develop a better workflow and to shape our long term vision for this project. The team has a fast response time and good communication skills.
MJ Klenk, RestoreCore
The Developmental Sprint® app, designed by myself and our Chief Business Officer and moved online by Speed & Function, enables individuals and teams to surface and overcome hurdles to success. Within three months of our initial conversation, we had our first beta-version to test with a client. Within six months, we were using it as a cornerstone of our business expansion. Our mission has always been to help people and organizations to get better at getting better. This app has enabled us to scale that mission within an organization by providing a common platform and language for identifying and acting on areas of improvement.
Andy Fleming, The Developmental Edge
Chief Executive Officer
The Developmental Sprint(R) app was my first time creating an online app. I needed a team with patience, compassion, and enthusiasm in order to help me execute against the plan. Speed & Function helped me to not only create the app, but to think through and practice how it would work. As a result, we now have an online app that supports our ever-expanding global business.
Claire Lee, The Developmental Edge
Chief Business Officer
I've been working with Nick and his team for about a year now. The quality of their work is by far the best I've ever seen. Even better, they are willing to spend extra time explaining what they are doing and to help you in any way possible.
Seth Goldstein
By far the best development company I've ever worked with — and I've worked with dozens. They are hands-on, precise, patient, highly-skilled, and actually care about what they are building. It's not a contract for them, they join in as if they are official members of your team.
Jason Sherman
The professionalism, care, and attention of the S&F team is fantastic. They take the time to truly understand their clients’ needs, they ask a lot of questions so that nothing is overlooked, and they deliver quickly and efficiently. We have finally found our forever dev team.
Sara Elliott, Encore Editions
Before our partnership with Speed & Function, we had two major outsourcing challenges: 1) poor project management/client services, and 2) lack of quality execution. Freelancers and companies alike produced amateurish deliverables that weren’t complete, the work purely transactional vs. part of our overall strategy. With S&F, we were relieved to see work that was completed end-to-end. We never have to pull teeth to get things finished. Their process demonstrates confidence in their expertise, and it’s helpful that the founder is here and available in Philly.
Before finding S&F, we had a handful of web developers that were unresponsive, slow to finish, and often didn't understand what we were trying to fix. In a very quick and responsive turnaround, S&F fixed one of our forms and implemented a few custom modules. They also supported us with some Drupal updates. Our website is now more manageable and secure.
22q Family Foundation
S&F has been instrumental in our project work, especially during ongoing month-over-month engagements. We look at them as an extension of our team. They have a deep pool of solid engineering talent. We never have concerns about the quality of their work or their ability to figure stuff out — that’s their greatest strength.
S&F is a solid business partner. Nick and his team are willing to do whatever it takes to make a project successful and to keep the customer satisfied. They are professional and thorough.
