Senior TypeScript Backend Engineer

I'm a Senior TypeScript Backend Engineer based in Madrid.

I have been building for the web since 2009, mostly around backend systems, product engineering and technical leadership.

I enjoy turning ambiguous product needs into simple, reliable software: APIs, integrations, data flows, internal platforms and the kind of backend foundations that let teams move faster without creating unnecessary complexity.

I am pragmatic with technology. I do not like chasing trends for their own sake; I prefer to understand the problem, test the trade-offs and choose tools that make sense in production. Lately, that also means using AI where it genuinely improves the way we build, review and operate software.

I work best in small, senior teams where ownership, clarity and good technical judgment matter.

I like to bond with the team, even on remote I care a lot about the energy of a team. I like useful meetings, honest conversations, quick pairing sessions, and making hard technical discussions feel lighter without making them less serious. I want the business to move forward, but I also want the people around me to enjoy the process of getting there.

I like staying close to the product I enjoy backend work more when I can see how it affects the product. I like understanding why a workflow exists, what users are trying to do, and where the technical constraints are shaping the experience. I do not need to own the whole product, but I do like being close enough to question assumptions and propose simpler ways to get the same result.

AI optimist I use AI to remove friction, speed up writing and exploration, and make product workflows feel lighter. The thinking still has to be human: understanding the problem, choosing the tradeoff, and deciding what is actually worth building. Humans provide purpose and criteria, AI provides fast research and writing.
