Notas de cybersecurity & tech
Whoami
I'm Ryan Camargo. I study cybersecurity and software, and I keep this site as a public notebook of what I'm learning — labs, CTF write-ups, networking, Linux, programming, and the occasional rabbit hole.
I believe in learning in public: writing things down forces honesty about what I actually understand, and leaves a trail that future-me (and maybe you) can follow.
