Biography

Web3 Experience

I have over 4 years experience in Web3 security. My speciality is finding impactful mathematical edge cases in protocols such as AMMs and lending protocols. I have a deep knowledge of Uniswap V3/V4 and other similar Concentrated Liquidity AMMs.

I am also a bounty hunter and have found several significant Critical/High severity exploits in live high-TVL protocols. I am in the top 100 on the Immunefi leaderboard. Write-ups of many of these can be found at 100proof.org.

A recent selection of private audits can also be found here

I am experienced EVM-based chains and Solidity/Vyper. I also have experience with Sui/Move, Stacks/Clarity and the NEAR blockchain.
