Rockstar🎓
Top SchoolGonzalo R is a Senior Software Engineer based in Montevideo with 15 years of experience building reliable web systems and open-source tooling across Elixir, Ruby, Rust and JavaScript. He currently leads end-to-end development at Mimiquate, shipping an Elixir/Phoenix Slack app and several Elixir libraries while contributing low-level fixes to prominent projects like Diaspora and the Rust ML framework Candle. Comfortable across full-stack, QA and devops responsibilities, he has repeatedly improved test reliability, refactored legacy systems, and resolved concurrency and backend edge cases in widely used libraries such as rake and rack-attack. Gonzalo’s work blends pragmatic maintainability with a security-conscious mindset—evident from his leadership on WebAuthn-related gems—and a preference for readable, energizing code. He’s as likely to be found improving Metal/CUDA kernel support as mentoring new teammates, combining deep hands-on engineering with steady open-source stewardship.
