About Me
Hi! My name is Rafael, I'm from Brazil, from a town called Ribeirão Preto — known as the "coffee land." So coffee isn't just something I enjoy, it's part of my roots. I've been fascinated by technology since I was a kid, thanks to my father, an electronics technician, who passed on many of his hobbies to me and my brother. My first contact with programming was at the age of 9, when my father brought home a Magic Computer, a Brazilian console with a few games and a coding tutorial in G-Basic. By 11, I was already creating websites about my hobbies, like Games and History (especially Ancient Egypt), and even writing bot scripts for MMORPGs. I started college in Physics at a renowned institution in the University of São Paulo, later switching to Computer Engineering. While studying and working, I decided to leave university and focus entirely on my career as a developer. Since then, I've worked on personal projects, joined early-stage startups that grew into major companies, and, more recently, I've been helping governmental and private organizations strengthen their security through compliance, training, and the development of cybersecurity products that ensure confidentiality, integrity, and reliability. Outside of work, I'm studying Mathematics, training in Brazilian Jiu-Jitsu, and, most importantly, truly enjoying fatherhood.
