As a Bug Bounty Hunter on HackerOne and Bugcrowd, I’ve responsibly disclosed critical and high-severity vulnerabilities across government agencies, financial institutions, and technology companies. I uncovered a critical vulnerability in Coinbase and earned the UK Ministry of Defence Hacker Coin.

At StackSecurity (TheInternetHacker.com), I deliver training in network security and penetration testing, and develop security assessment tools and payloads in Python and C. My projects include a Python honeypot that detects attack patterns and an email forensic analyzer for SPF, DKIM, and DMARC checks.
