Hi, I’m Jason.

My work spans developer platforms, infrastructure, and AI-supported products, usually alongside teams solving difficult systems problems.

This is a small collection of things I’ve built — side projects and experiments, mostly for fun and learning. Nothing for sale here, just work I enjoyed making.
