I operate at the edge of privacy, AI, and markets.

As AI makes software abundant, I'm focused on what still holds real value — private money, tangible markets, and human health.

Lore

I spent my early career building crypto platforms and protocols at meaningful scale — wallets, privacy systems, and DeFi — used by over a million people, securing significant value and enabling billions in volume. I've ethically disclosed critical vulnerabilities in late-stage protocols. I still angel invest, but most of my exposure is through public markets. These days I build where value persists as software gets cheap — private rails, tangible markets, and health. The specifics are below.

Most of what matters sits offline — family, being a dad, time on the road, and whatever physical project I'm currently in over my head on.
