I’m a builder with ten years of experience shipping web and mobile applications, scaling teams, and leading products from concept to completion.
My technical foundation is Ruby, Ruby on Rails, React, Postgres, GraphQL — although these days, give me a Claude Code subscription and I’ll build just about anything.
I’m currently transitioning onto the Bitcoin network. I lead local Bitcoin meetups, educate my community, and am deepening my knowledge of freedom technologies. I’m looking for a role that combines my technical depth with product and ecosystem thinking — where understanding both the business side and the engineering side is the actual job.
I’m very excited about the automation opportunities AI brings. I spend way too much time tinkering with openclaw 🫠
