Background
About
I write backend services and ML systems that run in production. Lately that's been FastAPI microservices, LangChain agents, and multi-modal models. I did my M.S. in CS at UC Riverside and I'm based in California.
Outside of work, I play guitar, sink hours into JRPGs, and tinker with OSS and agentic harnesses. I collect keyboards — HHKB is the only correct answer — and use Mario Zechner's pi agentic harness. I'm slowly teaching myself Japanese.
