CTF writeups, binary exploitation, reverse engineering, and bug-bounty notes. I compete on FlagYard and hunt real bugs. Everything here is from challenges I actually solved.

Writeups are published under /writeups. New content drops as I solve more.
What I do
- Pwn (binary exploitation) — ARM64 ROP, ret2libc, heap
- Reverse engineering & malware analysis
- Cryptography & forensics
- Bug bounty (access control, SSRF, XSS)
