← Cosmic Teacups

The speed is free. The quality is the entire game.

I’m a fractional CTO running AI agents that build real software for real customers. Every couple of weeks I write up what’s working, what broke, and what I’d do differently. The failures don’t make it to LinkedIn. This list gets everything, first.

  • Real production stories, not tool demos. Like the time one of my agents decided to cut a production release.
  • The operating model: containment, specs at the right altitude, making agents prove it instead of promise it.
  • What still doesn’t work. The failure list is longer than the win list, and more useful.

    Free. Every couple of weeks. Unsubscribe anytime, no hard feelings.
