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.
Expertise: Ruby on Rails, PHP, JavaScript, React, PostgreSQL, MySQL, AWS, CI/CD.
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.
I am an independent consultant specializing in computer security, compliance and governance with senior leadership experience. I have a background in standardization (ISO & W3C) as well as extensive expertise in free and open source software. My technical competencies range from embedded and systems engineering to high-level software architecture and data management.
If you have a project that could benefit from that expertise, I'm available for both fixed-rate and rolling contracts. Feel free to email me at: consulting@seabass.systems
I have a PhD in computer engineering, specializing in operations research, optimization, constraint programming, and integer programming. As an applied research scientist, I implement custom, production-ready solutions for a variety of optimization problems (scheduling, routing, rostering, etc). Recent work includes a sophisticated optimization model for the selection of indexes in Postgres, and a scheduling tool for workshops, used in hundreds of locations.
