Most of what I build is for work, and most of that I can't show. These are the AI systems I chase on my own time, in public: part research, part product, fully unfinished, and where a lot of the writing starts.
A personal AI coach I'm building from scratch: custom memory, open-source models, and a real evaluation framework.
The longest-running of these, and the one throwing off the most write-ups.
Read the build logA Warren Buffett style analyst: software that reads a company the way a patient value investor would, weighing the moat, the management, and the margin of safety instead of the noise.
Teaching a model to be slow and disciplined on purpose, in a domain that punishes hand-waving.
Read the build logNo schedule, no funnel. Just a short note when a build teaches me something worth passing on.
