A personal field journal
I build small things for people I love.
I’m Henry. Husband, dad, Marine, and technology leader. By day I lead a global team of technologists. By night I run a data center in my basement and ship small things because making them keeps me sharp. This is where all of it lives under one roof: the projects, the opinions, and the things that mean something to me.

How I lead and what I ask of the leaders I work with: people first, execution obsessed, and the five levels of initiative adapted for how we work now. Built on lessons from the Marine Corps through two decades of leading technology teams.

The talent grid I have run since 2015, written down: the two questions, the strata, the calibration rules, and a working grid you can place your own team on. Nothing you type leaves your browser.

The other side of the basement: a full enterprise stack at home, the AI harness that helps me run it, and the tools and write-ups I share back to the community.
