Stats 💻

At First, I study Coding and Algorithm(PS) with a little Math.
But I nearly quit studying this topic and do Hacking Tech Study.
I usually practice pwnable wargame in pwnable.tw, pwnable.xyz, pwn.college.
I also studied lectures with Dreamhack hard and solved their wargame/CTF for 3y and still working.
Now I’m trying to be a great researcher around the world, especially focusing on browser ex topic.
