[ About ]02 / 06

Most products die somewhere between idea and launch. I carry them all the way— architecture, code, deployment and everything between.

Since 2016 I've led projects end-to-end at enterprises and startups alike: gathering requirements, designing systems, and shipping web, mobile and AI products people actually use.

These days I build AI-first — Claude, Cursor and Antigravity write with me, and I bring what they can't: architecture, debugging and the judgment to know when the machine is wrong. One developer, several developers' worth of output.
