0xf00 : Hello World!

Hey! 🥸🤙

My name is Nicolas and I'm a Brazilian developer.... security engineer... pentester... architect.... reverse engineer... problem solver with more than 17 years of experience with IT in general.

I've started making money with computer/network repairs when I was 8yo and started coding since I was 10yo. At the time, I've created a Windows XP Malware with Basic to mess up remotely the sys32 structure. Since then I've never stoped learning about computers and the life arround me.

Fun fact: I've applied to Theoretical Physics and end up making Computer Egineering 😬 (Long story).
