Senior software engineer with 20+ years of experience specializing in Ruby on Rails and full-stack development. I’ve designed scalable backend services, built REST APIs, optimized databases, and delivered clean frontends. Experienced leader in mentoring teams and driving complex projects to completion.
As the sole developer of https://phish.in (https://github.com/phishin), I designed, built, and maintain an open source project that has grown over 12 years to serve more than 120,000 monthly active users with 99.99% uptime.
Previously at Weedmaps (7 years), where I designed and maintained backend services, led cross-functional teams, and mentored engineers. Other experience includes Red 5 Studios (AAA gaming company where I built backend microservices, payment integrations, and in-game UX) and Dawnbreaker (US federal contractor where I built web apps for state and federal agencies).
Looking for remote-only Ruby on Rails work. Open to full-time, contract, or consulting roles.
