Profile

I connect language models to working products: tool-calling LLMs, long-term memory with pgvector and an end-to-end voice assistant (Whisper → LLM → XTTS-v2). I build Python/FastAPI back ends, Vanilla JS/TypeScript front ends and Linux/Windows desktop packages on my own, working with coding agents such as Claude Code and checking their output with automated tests. 20 of my changes have been merged into 11 open-source projects.
