About 01

Full-stack engineer with 15+ years across the stack. Spent seven years at GitHub working on everything from audit-log infrastructure handling billions of events to the public GraphQL API. I specialize in Ruby on Rails and React/TypeScript — modernizing monoliths, building scalable front ends, and leading teams through complex migrations.

U.S. Air Force veteran. Remote since 2011. I like hard problems and clean code.
