Complex models become workflows people trust.

From financial models to production AI, I build products and systems that help people make better decisions in complex systems.

Portrait of Jose Cao

I spend my weekdays building AI products and my weekends riding my motorcycle, surfing, or helping my girlfriend keep her 2009 Jetta alive. In between, I’m usually reading about AI, economics, or whatever has captured my curiosity that week.

If any of this resonates, I’d love to talk over coffee or while sharing some mate.

Projects & Essays

What I’ve built and what I’m still exploring.

Over the past year, many of these projects have revolved around a simple question: how do I make better decisions? That led me from reflection systems, to personal knowledge, to AI interfaces that help organize and challenge my thinking.

Occupying my thoughts

An obsession is free motivation. If it’s pointed at something worthwhile, pursue it to the max. Don’t seek balance. It will become part of your identity.
