My name is Pablo, Computer Engineering student at the University of Deusto. I like working on low-level programming with C/C++.
In this website you can find articles and projects. This page also documents some Capture The Flag (CTF) competitions in which I have taken part as a member of 0xDecode (Deusto Electronic Club of Developers and Engineers). You can find technical explanations on how I solved some challenges in the writeups section.
