About
Joris Obert
10+ years building mobile apps. Started with native iOS/Android before going all-in on Flutter from its early days. Now I handle the full chain: mobile frontend, backend, store deployment, and AI integration.
26 freelance missions delivered with a perfect rating, personal apps downloaded millions of times, and still the same drive to build products that just work.
Based in Paris, fully remote.
