Senior software engineer based in Spain 🇪🇸.
Day to day: Go, Terraform, fine-grained authorization, and the backend infrastructure underneath. Usually on problems where they pull on each other. I lean broad rather than deep, which is useful when the problem doesn’t fit a single specialty. Most of what I build is in service of developer experience: the small frictions that compound into real costs when you ignore them. Always up for a hard problem, always looking to make the next one less painful.
Off the clock, I’m a serious foodie. I love hunting down new restaurants, cooking things I’ve never tried, and traveling to cities with a reputation worth eating my way through.
