Systems Engineer @ Cloudflare

About

Hello there!I'm David, 23, I'm a Software Engineer at Cloudflare and Computer Science and Engineering MSc graduate at Instituto Superior Técnico, in Lisbon. Since I was little, numbers have followed me everywhere I go. And computers too! So there's no surprise that I'd join a course that allowed me to mix both.Although I majored in cybersecurity, I couldn't put aside my long-lasting passion for Maths - as such, my MSc thesis was focused on Portugal's (contentious) consumption patterns of psychiatric drugs.Other than my academic efforts, I'm an avid music listener, always looking for new genres and styles to discover. In my free time, I also play games, watch anime and read manga. And these interests took over my life in such a way that I've been learning Japanese for over three years now!
