A dated log of side projects: AI agent systems, enterprise content platforms, and games built with my son. Explore the diagrams, implementation notes, and source repositories.
Projects over time
Apr 2025 - Sep 2026 · the main run · one 2024 prologue below
Bars run first commit → last build commit, so overlaps are visible. A few repos kept getting small restyles after their bar ends. Click one to jump to the writeup.
How they were built · each writeup below carries one of these labels
- spec-first A PRD and tech spec before any code, with tasks numbered from the spec. The oldest habit here; it started in 2025.
- incremental specs No big up-front plan. A dated spec folder per release, then build, tag, and repeat.
- ad hoc Conversation-driven, no spec. Some of the quickest builds on this page went this way, and it shows in their scope.
- dark factory An unattended harness planned, built, and verified the work. I read the commits in the morning.

Built with Bruce
The father-and-son repos
Not every project is an agent mesh. Three of the repos are games designed with my son: he supplies the game design, I supply the AI, and an idea becomes something playable before bedtime.
