At Centauri Media LTD, I develop and ship features across 10+ production React Native and Next.js client projects. I integrate Stripe payments, marketplace payouts, and subscription billing across web and mobile.
At GreenPurpose e.K., I built and documented a REST API with hashed partner keys and secure file uploads, and created 200+ integration and end-to-end tests with Vitest. I also built a headless RSC form library so partners could add the energy certificate flow without rebuilding it.
I built evento, a Next.js and Supabase attendance app that handled 50,000+ check-ins across 30+ events, cutting check-in time from 10 seconds to 2 seconds. On XR Vision, I developed a React Native app for on-device plant disease classification and built a Python FastAPI backend for predictions with saliency heatmaps.
