About
I'm the founder and CTO of Helen's Foundry. Google fired me in April 2026, and I've been building Helen's Foundry since.
Recently architected the open-source Google Workspace CLI in Rust, 20k+ stars and #1 on HN.
When I'm not coding, I'm usually running long distances in the mountains of Colorado.
