Hey, I'm Jasper

I build apps, mostly with React Native, but also web products and the backend pieces behind them. Based in Belgium.

Build iPhone apps by chatting

Apped lets you describe an iPhone app in chat and get back a real React Native app running on your phone. I built the mobile app, the backend, the sandboxed runtime for each generated app, and the AI loop that edits code and streams the result back live.

Hunting Game

GPS chase game

Hide and seek, but your phone tracks everyone. Hunters chase runners across the city using real-time GPS. Built the whole thing — iOS, Android, Watch app, multiplayer backend.

App Store toolkit

Managing App Store reviews sucks. This handles it — AI-generated responses, metadata management, the boring stuff automated so you can ship features instead.
