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.
I asked 65 vision models to rank Miko's likely breeds from the same evidence given to humans, then compared their guesses with her DNA results.
My 26-hour and 28-hour pacing plans, aid station splits, fueling, drop bags, lights, and weather strategy for the 2026 San Juan Softie 100.
A writeup of a small agentic system I built to triage my Gmail inbox, using Claude subagents to organize and assess messages.
Why I embedded an MCP server in a native Rust prose editor so an AI agent can drive, inspect, rebuild, and verify the running app.
Every layer from App to API to MCP loses fidelity. An exploration of what gets lost and why it matters for enterprise APIs.
