Engineer first. Now an operator.

I'm Operating Principal for Technology & AI at Clearhaven Partners, helping portfolio company engineering teams get real leverage from AI and evaluating the technology behind new deals.

Before any of that, I was a combat medic in the U.S. Army. It still shapes how I lead: triage first, team first, outcomes over outputs.

This blog is where I write up what I build: agentic engineering on twenty-year-old codebases, hybrid setups that pair frontier and local models, and the unglamorous infrastructure that makes AI pay off. Most posts come with the setup and the numbers.
