About

I’m a sophomore Computer Science student at University of São Paulo (USP), in Brazil. I’m mostly interested Computer Systems Security, Computer Networks, Linux and Open Source Software development. My hobbies include, but are not limited to, Parkour (“Être et Durer”), learning French (currently C1), writting and destroying trailling spaces -- I really hate trailling spaces.
