About

Cybersecurity engineer based in Spain with a background spanning both offensive and defensive security. I finished first of my promotion in Computer Science at Universidad de Zaragoza before completing a bilingual Master's in Cybersecurity at Universidad Carlos III de Madrid.

Day-to-day I operate within a SOC, investigating high-severity incidents, performing forensic analysis, and conducting threat hunting in response to active APT campaigns. Outside work I maintain a homelab, contribute to open-source projects, and grind CTF challenges on Hack The Box and TryHackMe.

I also completed a marathon — which says more about my stubbornness than my pace.
