Projects

Six things I've built recently, spanning trading infrastructure, manufacturing automation, hardware, and research tooling. Each links out to a page with more detail.

A price-time-priority matching engine that streams a ClickHouse-backed trade tape and replays it session by session, with a live depth-ladder GUI.
