Building and Thinking
One-off posts, plus a few ongoing series. Click a series to read only its posts.
- Autonomous companiesOngoing efforts to build and grow several products sustainably. I want to be as effective as I can (10x+), solo.
- Signals over vibesThe harnesses I build across products to work on signal instead of vibes, especially after sprints.
- Society essaysReading books and writing about business models that put respect for all life first. I'll turn my theories into action, eventually.
- Product postsTechnical breakdowns of what I'm building. Usually post-sprint reflections.
- Game devArt plus coding = short games I make on the side.

- Why I moved Mortrel's encryption to the server

I did plan-driven development and had Codex review every plan and every diff. The codebase rotted anyway. Here's the harness I built for V2 — and why yours will look nothing like mine.
- A tale of two crons
I tried to fix a one-line SQL bug. It turned into ~180 LOC deleted, a refactor, and three new design checks I now run on every plan.
