Voice-first clinical training simulator — I'm co-founder and CTO. Medical students play the doctor: patients arrive, you talk to them in real time, order tests, treat, disposition. An attending physician agent watches every decision and grades it against the published guideline (NICE, ESC, AHA, GINA, GOLD). Live at medkit.clinic, invite-only.

Source-grounded Quran Q&A with hybrid RAG. 6,236 verses, 15 translations and 6,237 tafsir chunks in a pgvector store with HNSW indexing; tsvector lexical search (Turkish diacritic-insensitive FTS) fused with semantic search via Reciprocal Rank Fusion. The LLM never produces scripture — Arabic verses are always served from the data layer with references, so it can't hallucinate. Live on the App Store.

Your own computer's coding agent, from your phone — not a hosted copy of it. A daemon on your machine drives the real claude or codex process in your repo, signed into your own account, and speaks WebSocket over your tailnet. Approvals land on the lock screen with the exact command; turns keep running when the phone loses signal. Ships with a desktop panel that watches every machine at once.

Real-time automated trading bot consuming Binance WebSocket streams and executing custom strategies. Deployed for banking clients (DenizBank, Akbank). My code trades better than my instincts.

End-to-end YOLOv5 detection pipeline for ship electric charging sockets with auto-locking. Anchor optimization, real-time inference. Published in IEEE.
