Summary
🤩
Rockstar🎓
Top SchoolSimon Contreras is a pragmatic tech lead and product engineer with 15+ years building and scaling backends, APIs, and full-stack products across startups and high-traffic platforms. He combines hands-on mastery of Node.js, PostgreSQL and cloud platforms with experience in Python, GIS, BigQuery and AI tooling, moving fluidly between greenfield builds and complex legacy codebases. As a founder of two companies and former CARTO senior engineer, he pairs product-minded engineering with operational rigor—SOC2 compliance, observability, and extensive automated testing are hallmarks of his work. He mentors teams, improves processes, and prioritizes UX and measurable product impact over developer convenience. Based in Cantabria with a global remote track record, he’s equally comfortable shipping APIs used by millions or iterating on niche beta-testing products like Stomio.
