Biography

I built my first Ethereum smart contracts in 2016, and I joined MakerDAO full-time in early 2018. At Maker, I initially worked on the testing and integration tools that connected our smart contracts to the frontend, and I was later promoted to Head of the JavaScript Engineering team. During this time, I contributed to some of the first major DeFi and blockchain governance webapps.

In 2021, I became CTO at an NFT analytics startup before transitioning into independent consulting and technical advising in 2022. By mid-2023, my consultation and advising focus had become exclusively about security. I've since conducted solo smart contract audits (using fuzz and invariant testing) and performed frontend audits and penetration tests for prominent Ethereum projects, and my solo smart contract audits alone have secured approximately $60 million in TVL.

My approach is practical and test-driven, emphasizing security, correctness, and real-world application.
