MVP Development
From idea to working product in 6-8 weeks. React, Next.js, Supabase. Designed to validate fast and scale when it works.
Freelance Developer in Berlin — React, Next.js & iOS
I help early-stage startups and established companies build their first product — or scale the one they have. Based in Berlin Mitte. Remote-ready.
What I build
iOS & Android Apps
React Native / Expo apps shipped to App Store and Google Play. I've done it with Orivela — I can do it for your product.
Full-Stack Web Platforms
Next.js 14, TypeScript, Tailwind, Supabase, Vercel. 10+ platforms built and shipped to production.
Founder as a Service
Not just code. I think in systems and products. Early-stage startups hire me when they need someone who builds and thinks like a founder.
