01. About Me

I'm a Blockchain Security Researcher passionate about finding vulnerabilities and building secure Web3 applications.

I've discovered critical vulnerabilities in ThorChain's Rujira protocol, approved by the ThorSec security team. Currently working as a Smart Contract Developer at iEscrow.io, where contracts were audited by CertiK and I resolved all audit findings.

My journey started with curiosity about DeFi security. What began as learning Solidity turned into hunting vulnerabilities in production protocols and landing remote blockchain roles. I specialize in smart contract security, DeFi attack vectors, and secure development practices.
