Senior Ruby on Rails engineer focused on rescuing and modernizing established products.
I’m a good fit when a Rails application is already important to the business, but releases have become slow or risky, production is unpredictable, an upgrade has stalled, or the team needs someone senior to own a difficult technical initiative without proposing an unnecessary rewrite.
My work covers production debugging, Rails and PostgreSQL performance, upgrades, test stabilization, legacy cleanup, infrastructure, and payment or CRM integrations. I can take a problem from diagnosis through implementation and production.
I’ve worked on products including Napster, Gimme Radio, Roomsie, Nexible, and several Rails/Spree ecommerce systems.
I also build my own products: SayTrue.ai, grounded AI customer service across voice, web chat, and social channels; ClearMX, an email verification platform for small SaaS teams; and Movieo, a movie discovery and tracking product covering more than 250,000 titles. Building products myself keeps me close to engineering, product decisions, infrastructure, operations, and the commercial realities of shipping software.
For founders looking to launch something new, I also offer focused micro-SaaS builds and small SaaS MVPs through Bytecode for €10,000. We agree on a realistic scope upfront, centered on one core workflow, with authentication, billing, and a production deployment.
I’m open to senior or lead Rails roles, long-term contracts, part-time consulting, and focused rescue engagements.
