Hasan Sheet

I am a cybersecurity researcher and bug bounty specialist with over two years of focused experience in web, mobile, and enterprise security. I research, identify, and responsibly disclose high-severity vulnerabilities, including iOS-level issues acknowledged by Apple.

My work spans advanced penetration testing, in-depth reconnaissance, logic-flaw exploitation, and exploit development. I have a proven track record on HackerOne, Intigriti, and Bugcrowd, delivering impactful reports across financial, technology, and e-commerce sectors.

I build and use custom automation tools and scripts in Python and Go to scale discovery and improve testing efficiency, while leveraging tools such as Burp Suite, OWASP ZAP, and Metasploit. I partner with security teams and global platforms to validate findings and support remediation.

I hold recognition from industry vendors and organizations for responsible disclosure and critical vulnerability discovery, and I bring a collaborative, methodical approach to strengthening digital security through continuous research and ethical hacking.
