I'm the Principal Technical Director at SeQura, a fintech based in Barcelona, where I joined as the third engineer. I lead technical strategy, execution, and AI adoption, but what I actually do is closer to applied curiosity: understanding how things really work, questioning the assumptions we stopped questioning, and building the conditions for the next phase of growth.

Most of the interesting problems in software aren't about code. They're about what happens when systems grow faster than the organization's ability to understand them. A monolith that worked beautifully for twenty engineers becomes a minefield at sixty. Patterns that once enabled speed start generating friction. The people who saved the company in its early days get stuck solving the same problems because nobody built the conditions for them to grow beyond that.

I think a lot about these inflection points. The moment when "move fast and fix later" meets "later is now." When you realize your technical debt isn't really technical: it's a coordination problem, a people problem, a systems-thinking problem. My work sits at that intersection: making large, messy, real-world software systems more understandable, and making the teams around them more effective.
