About

Systems engineer. I build things end to end — the mobile client, the API, the warehouse it reads from, and increasingly the agents that operate them.

Lately most of my work sits at the boundary between products and LLMs: agents that drive real interfaces, natural-language layers over business data, and the unglamorous plumbing that makes either of them reliable enough to leave running.

Open to software engineering and AI engineering roles.
