About
Senior Full-Stack Developer with 7+ years of experience shipping production web and mobile applications. My primary stack is Next.js, React, TypeScript, and Supabase, with deep backend experience in Node.js and AWS.
Right now I'm building two client products in parallel: a UK-based flight school directory (Next.js, Supabase, Stripe, map-based search) and a pet recovery platform (Supabase auth, edge functions, real-time features). Before that, I built a React Native mobile app from scratch for an AI startup (331 commits, 586 tests, custom SSE parser, encrypted API integration) and migrated 1,640+ users from AWS Aurora to Supabase with zero data loss for a client through Arc.
Earlier in my career, I founded and ran a 14-person dev agency, cut AWS costs by 45% through infrastructure optimization at W3YZ, and built a SaaS product serving 3,000+ users.
I work best with founders and small product teams who need someone to own the full stack, make architecture decisions, and ship without hand-holding. I run structured async communication, maintain high test coverage, and protect production with security audits and RLS policies. Based in Istanbul (UTC+3), available 8 AM to 11 PM and comfortable with any overlap arrangement.
