Why the founders chose us as their technical team

The Problem

Since the very beginning of React Native, Expo has been building an entire toolchain around it, aiming to facilitate and accelerate the development of mobile applications and beyond. React Native developers were rare when the technology was first was open-sourced, and Expo needed a team that could match their internal expertise. They reached out to App & Flow to help them to accelerate the development of their toolchain.

The Solution

Because we were one of the first teams to specialize in React Native, we were able to quickly jump in Expo’s codebase and start contributing. From building native modules to developer tools and bug fixing, we have been active contributors on Expo since 2017.

"App & Flow have supported us immensely with all aspects of software development. They bring an incredible amount of knowledge and professionalism that has helped us build software more efficiently. They have consistently provided the best solutions in a reasonable timeframe and always exceed our expectations. At fittcoach, we consider them to be integral to our organization and I would highly recommend them to anyone looking for a rockstar team of developers!"
