Hey! I’m Andrew (snowbird91)
I’m a high school student intersted in cybersecurity and CTFs. I usually bounce between two teams:
- tjcsc — captain of my high school club team. 4th worldwide, 1st US
- 0xf1sh — secondary roster for CTFs. 308th worldwide, 26th US
Focus areas
- Forensics, reverse engineering, OSINT
- Comfortable jumping into crypto, pwn, web, and misc when needed
What I’m up to
- Planning lectures and writing challenges for the club in-house CTF
- Learning how to write write-ups
- Deepening my knowledge of pwn, learning new techniques
- Making this website better :)
