Available for work

Hi, I'm Matthys

I build mobile apps with React Native and Expo — always on the latest SDK. I'm Head of Mobile at Ekklo, a fitness coaching platform, and I write about what I learn building it.

01/about

I build apps people actually use

Six years in, I'm a React Native & Expo developer — Head of Mobile at Ekklo and a React Native dev at weshipit. The apps I build are used daily by thousands and stay highly rated on the App Store and Google Play, because I build them to be fast and to scale.

One grid for all your simulators — run multiple Expo projects on multiple devices in parallel, without the alt-tab dance. It routes each project to the right simulator automatically.
