I'm a co-founder of Second Brain OS, where I build AI-powered "second brains" for companies — persistent, structured knowledge systems that don't just remember your business, but know it and execute on it. Memory, understanding, and agents that actually run the work: the full loop.

I care about building things that work in the real world, not demos. I'll happily spend 30 hours on one hard case rather than ship a prototype that falls over.

The full loop — not just a brain that remembers, but one that acts:

• Remember — second-brain vaults: CLAUDE.md-driven knowledge systems that agents read from and write to across sessions
• Know — structured context, ICP, brand and strategy that AI can reason over instead of re-learning every time
• Execute — custom skills, agents and "engines": PDF→Markdown pipelines, quote generators, CRM setups, Make.com flows that run real tasks

Free, working things you can clone and use, not just showcases:

• founder-os — an open-source "second brain OS" template for founders. Folder structure, agent instructions, and a psychologically-grounded onboarding interview (brain-setup) that fills your context files for you. (Click "Use this template" and go.)
• trader-os — an AI-native second brain for traders, built for Affluency and running in production: 21 specialized coaching skills, live trade data over MCP, autonomous routines. MIT licensed.
• More coming as I clean things up for public use.
