Projects

Fourteen years of things I’ve built: open source, client products, and community work.

Most of it is Python and Django backends; lately it’s AI agents. These days I lead engineering on Rosey, Fueled’s AI-native delivery platform. Now has the details.

This is a selection. Smaller things live on GitHub, and some client work isn’t public.
