01 / about

About Me

I'm a full-stack engineer (B.Sc. Trakya, 2024; M.Sc. ongoing) building ReHeal, an early-stage digital health product: a React Native patient app, a Next.js clinic dashboard, and a SUT/SGK rule engine for pharmacies. Before that I interned at Jotform, Sixfab, and Parentwiser, and spent a short stretch at Elmali Tech shipping Next.js apps. I also work with ML when the problem needs it (BERTurk, XAI, ADS-B), but the day-to-day is TypeScript, Next.js, Expo, Supabase, Node. Open to full-stack roles.
