Biography

I work on the gap between deep learning that looks good in a notebook and systems a business can actually rely on. Right now that means autonomous LLM agents with LangGraph, and standardising how they fetch context and call tools through MCP. What I care about is closing the distance between a demo and something that runs in production for months without anyone babysitting it — which usually comes down to orchestration, data infrastructure, and knowing whether the right answer is a model, an agent, or a hundred lines of boring reliable code.

Alongside product work I keep one foot in research — five peer-reviewed publications in AI/ML and next-generation networks — because production systems turn out better when someone in the room has read the papers.
