Over time, he has reported critical vulnerabilities to 50+ Australian companies and received bug bounties from Uber, Apple, Mastercard, Octopus Australia, MagicLeap, and Paysafe.

In the industry, he played a critical role in defeating Infosys in 3 major RFPs while being part of underdog teams. Beyond corporate challenges, he took the lead in India's first blockchain token deployment, successfully developing and listing tokens on the Ethereum network.
