Who is
tn27x3b0?

I'm a self-taught security researcher and developer focused on finding and responsibly disclosing vulnerabilities in web applications, APIs, and network infrastructure.

When I'm not bug hunting, I'm competing in CTF competitions, building open-source security tools, and writing technical writeups to help the community level up.
