Firmware to frontend, CAD to cloud. I take an idea from bare silicon to a shipped system — usually the whole stack, usually solo.

Most builds need a team of specialists. I compress that team into one person — the one who's comfortable at the oscilloscope and in the deploy pipeline.

A career across aerospace, cybersecurity, electrical, and robotics taught me that the interesting problems live in the seams — where firmware meets cloud, where a mechanism meets a model. I build across those seams: watchdog-guarded motor controllers, real-time video pipelines, full-stack marketplaces, native iOS/watchOS, AI-in-the-loop tooling, and the CNC-machined hardware to house it all. If it takes electrons and code to make it real, it's in scope.
