I build things that learn. Software that gets sharper with use, neighborhoods that get more generous, trading systems that run on their own.

Right now: Bountiful Garden turns the lemons rotting on my block into someone's lemonade. OpenClawBrain gives OpenClaw agents a long-term memory so they stop solving the same problem twice. Project Pelican is an options desk with no desk — it trades while I sleep.
