development

Rock-solid, enterprise-grade development.

The modern web isn’t just for static websites and content consumption. It’s the most open, flexible, and immediately accessible application runtime available today, both via mobile and desktop browsers. Modern web applications use architectures that make them more like their native app counterparts on iOS and Android than apps of the web’s old guard. Business logic, instead of living on the server, now resides primarily in the browser.

Over the past five years, the tools available to developers to help build these kinds of applications have proliferated and matured. These improvemets allow for the reuse of back-end systems and APIs across native and web platforms, faster development timelines, reductions in build and maintenance costs, increased flexibility, and advanced user experiences (UX).

Our Web Applications Team has deep experience with Backbone.js, a lightweight framework that we we’ve used to launch dozens of apps, from high-profile media streaming applications to sophisticated HTML5 games.

Systems architecture

Our seasoned architects help our clients evaluate options to bring their projects to life. The best mobile experiences require a robust back-end foundation. Our teams have years of experience integrating with back-end and middleware systems and can evaluate alternatives based on cost, time to market, implementation risk, performance, scaling, and security considerations.

Accessibility

When everyone can use a product, both the user and the company benefit. We build products that exceed accessibility requirements by both using automated tests, and consulting with real users who have visual and other impairments.

As your digital innovation partner, we stay up-to-date on the latest accessibility requirements and technologies. Will it work with a screen reader? Is the contrast high enough? Does it include resizable text? We consider and resolve all these questions—and more—no matter the platform.

Tactics
  • Usability requirement gathering
  • Low-vision personas
  • Usability testing with visually impaired users
  • Automated accessibility testing
  • iOS and Android accessibility
  • JAWS and NVDA
  • ARIA best practices

Mobile backend engineering

From the earliest stages of product conception and strategy, our API architects focus on building a custom solution to meet your specific needs. Whether it’s integrating with your existing systems, developing a middleware-based approach, or building a custom, from-scratch solution, our engineers have done it.

QA and testing

We consider quality assurance and testing absolutely critical to every project we take on—that’s why our QA team members are involved from day one through product launch (and after). We aren’t satisfied until your app runs the gauntlet of our automated and manual tests, and makes it through intact.

  • Background checks

React

In 2013, Facebook announced ReactJS, a front-end web framework that radically reimagined how web apps can be built. React helps optimize performance, giving users smoother scrolling and faster response times. It also enables developers to reuse code intelligently and, as a result, our clients get features built faster for less money.

Our Web Apps developers are experts in bringing React’s considerable strengths to bear for our clients. Our experiences deploying large-scale React applications and developing a shared and battle-tested toolkit of components have positioned us as thought leaders in the space. We’re continuing to innovate new ways of using the game-changing set of tools associated with React, including pioneering development work on React Native.

Expertise
  • Isomorphic / Universal Apps
  • Redux
  • Flow
  • React Router
  • CSS Modules
  • TypeScript
