Ruby on Rails Architecture Leadership PostgreSQL Hotwire Sidekiq AWS Microservices CI/CD

Full Stack Developer and Backend Tech Lead with 10+ years building systems that hold up under real pressure. From streaming infrastructure serving millions of users to enterprise payroll processing for Fortune 500 companies — I've been deep in production-grade code across every scale.

I don't just write code. I architect systems, mentor teams, and own outcomes. Every technical decision maps back to real-world impact — because good engineering creates genuine value for real people.

Currently leading backend architecture at Rakuten TV, one of Europe's premier streaming platforms. Based in Barcelona.
