About

I've been building software professionally for nearly two decades. These days I build and run my own products, from the API design through to billing and operations.

AI agents are a big part of how I build now, and I write about what works and what doesn't in the Notebook. I also take on selected remote product engineering contracts.

Before my own products I built point-of-sale systems for 500+ stores, mobile apps with 500k+ downloads and an identity API, and led engineering teams of 25+ developers. The list is on the projects page.
