Nine intents, two games
How I built two browser games with intent-driven development, from the first idea to a spec marked built, and what three days of it taught me.
Engineering manager
I build agentic AI on Rails, and the teams that ship it.
I'm an engineering manager at Cezanne HR. I've spent ten years in software, the last five on Rails SaaS platforms.
Now
These days I build agentic AI into Rails products and lead the teams that ship it. That means the agents themselves, and the pipelines, guardrails and review loops that let agents ship work without the wheels coming off, measured rather than assumed.
This site is one of those systems. Agents propose the changes, the checks decide what ships, and I set the conditions. How it's built.
Selected work

Rates new production errors against SLA severity, run in shadow mode until its calls could be trusted.
Latest writing
The job is the conditions
Becoming an engineering manager and running seven agents on this site turned out to be the same lesson.
Creations
Fretwork
A songwriting tool for guitar: pick a key, build chord progressions, hear them, see the shapes and change key between sections, with the theory explained as you go.
Passing through
A small four dimensional universe, and what the beings in three, two and one dimensions can see of it.
Conditions
A toy model of a team, and two ways to lead it.
