Ruby on Rails developer based in Argentina 🇦🇷, building and maintaining production apps, APIs, and background systems with AI in the loop.
- Rails, end to end — APIs, Postgres, background jobs, AWS deploys
- Test-backed refactors — RSpec, Capybara, killing tech debt without breaking prod
- Accessibility & performance — WCAG 2.1 AA, query optimization, real cost reductions
- Open source — contributor to Rails and Omarchy
How to ship Rails faster with AI without losing the craft — prompts as conventions, skills as documentation, agents that respect the Rails Way. I write about it at OffTheRails.
