Full stack developer and wearer of many hats.
Hello, I'm Devon the Developer. I'm a senior/staff level full stack developer with over a decade of experience and strong proficiency in Rails and JS (Node/TS/React/etc). I'm comfortable at every level of the stack, from container to component, and I've worked both with and on AI agents extensively.
I've taken ventures from initial sketch to launch to scale, operated at high user volumes with minimal downtime, and led small teams, mentored, and run workshops along the way. Whether it's user-facing feature development, business logic optimization, infrastructure as code, auditing AI workflows, or leading a team of engineers, I'm your guy.
