About

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. top 10 United States team on CTFTime (as of 12/25/2025)
  • 0xf1sh — secondary roster for CTFs.

Focus areas

  • Forensics, cryptography, OSINT
  • Comfortable jumping into rev, 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 :)
