This is Mystiz, a made in Hong Kong 🇭🇰 software engineer. Currently stationed at Taiwan 🇹🇼 working for Google.


I am better-known as a Capture the Flag player and I hack with Black Bauhinia as a former captain and Shellphish. I like to struggle at crypto and reverse challenges, and sometimes pulling my hair on ad hoc problems. You may expect me doing writeups on the challenges I liked (if I have time). I played DEFCON CTF Finals thrice on 2019, 2020 and 2021, and a finalist for CODE BLUE CTF 2019.
