Hi, I'm Derek.

Software engineer — research and trading infrastructure for a living, aviation and motorsport for fun.

For most of two decades, the day job has been building data and research platforms for quantitative trading firms. The projects here are what I build for myself — the professional history is on LinkedIn.
