Hi, I'm K4L1
I break things for a living — then help fix them. Specialized in finding critical vulnerabilities before the bad guys do, and building secure applications that withstand real-world attacks.
About Me
$ whoami
I'm a security researcher and developer with 8+ years of experience breaking — and building — web applications. I've found critical vulnerabilities in products used by millions, earned recognition on major bug bounty platforms, and helped organizations strengthen their security posture.
$ cat philosophy.txt
Security isn't just about finding flaws — it's about understanding systems deeply enough to see what others miss. Every bug I find makes the internet safer for everyone.
$ cat approach.txt
I combine deep technical knowledge with creative thinking. My methodology goes beyond automated scanners — I understand business logic, data flows, and how attackers actually think.
