Full-stack developer · AI products · Denizli

I build AI tools for work that has to be right. Legal research and drafting at Ravon today, lending systems at a bank before that.

Full-stack developer working mostly with Python/FastAPI, Next.js and TypeScript, with a Java/Spring Boot background. At Ravon Group I work on Ravon Sage, private AI for law firms that answers with its sources and can run entirely on a firm's own servers. Before that I spent years in fintech, building KYC services and partner integrations at Fibabanka, where reliability mattered more than novelty.
