Projects

Products built outside the job, out of interest.

• Turkish Legal AI Platform

  Personal project · full-stack

  A RAG system over Turkish court decisions drawn from 12+ legal institutions.

  Court decisions from the yargi-mcp data source are indexed and searched semantically: BGE-M3 embeddings are held in Qdrant, retrieval and reasoning are orchestrated with LangGraph over the Claude API, and the application layer is Next.js 15 with Supabase providing PostgreSQL and auth.

  Personal project · mobile

  An onboarding quiz, a selfie and a 30-second voice sample are turned into a five-years-ahead persona.

  That persona speaks back in daily audio messages recorded in the user’s own cloned voice. Messages are generated by an LLM and passed through safety classification before they are spoken; the voice is cloned with Inworld TTS and the app is built in TypeScript on Expo/React Native.
