Introduction
I'm a college student who loves to study cybersecurity and development.
Among them, I like to play CTF and Wargame.
Besides computers, my other hobbies are chess and climbing.
My main fields are binary exploitation and web hacking, but I'm also trying to be good at reversing and cryptography.
Recently, I have been doing Linux Kernel Research at Theori.
