About
You can call me shaobingbujiadan. I'm a Taiwanese high school student and a CTF player for Bamboo Fox, mostly working on web security, reverse engineering, and cryptography challenges.
This site is where I keep detailed writeups, competition notes, and the ideas I want to revisit after each event.
