About
I'm a software engineer with a background in physics and over 30 years of experience building systems across web, backend, and infrastructure.
I care about understanding how things work — from distributed systems to color perception — and tend to focus on depth over breadth.
Outside of engineering, I've been involved with music for decades, which still influences how I think about systems, structure, and timing.
