Sobre mim
I build and ship real products, not demos. 3.5 years as a full-stack engineer: React Native apps shipped to the App Store and Google Play, an AI video platform serving ~500 users, and RAG search systems (hybrid BM25 + pgvector + reranking) used in production. I help founders who built with Lovable, Bolt, Replit or Cursor get to production: fix bugs, secure auth and APIs, publish to the stores, and add AI features that work. Stack: React Native, Expo, Next.js, NestJS, Supabase, Postgres, Go, Docker. Clear scope, daily updates, clean handover.
