About
Hi there, I'm Gavin.
I build applied AI and ML systems, with a focus on LLM products, agentic systems, and inference optimization.
Recently built Protostar, a browser copilot that brings Cursor-style intelligence to web browsing.
Beyond work, I build side projects, write about what I learn, and play RPGs like Elden Ring and Dying Light in my downtime.
