About

Offensive security, real-world impact.

Who I am

Cybersecurity researcher & bug hunter specializing in penetration testing, bug bounty hunting, and vulnerability assessment. I report security flaws to organizations like Apple, Google, Toyota, and NASA — and compete in CTFs and security labs when I’m not hunting bugs.

Currently pursuing B.Tech CSE (Cyber Security) at Silver Oak University, focused on web & API security, secure coding, and offensive techniques.
