I’m an EVM security researcher, Lead Senior Watson at Sherlock and Zenith auditor at Code4rena, with more than 3 years of experience working in the DeFi ecosystem as both developer and security researcher. I've conducted audits for a wide range of DeFi projects, including lending protocols, stablecoins, omnichain systems, and account abstraction, identifying vulnerabilities in top live protocols like Safe, Yearn, and Renzo.
I began my blockchain journey as a developer for the NFT lending protocol Unlockd, where I led contract development and security efforts. This experience deepened my passion for smart contract security, and I quickly transitioned to focus on vulnerability research full time.
With a strong focus on lending and cross-chain protocols, as well as assembly-heavy implementations, I have contributed to important standards like ERC6551, a Non-fungible Token Bound Account standard, following an audit of its implementation. My deep low-level expertise includes leading security reviews for projects developed entirely in assembly.
