This public repository serves as a profile of my security related work.
I am working as a security researcher focusing primarily on Ethereum/EVM at Spearbit. My role at Spearbit is LSR (lead security researcher).
If you want to work with me visit my Cantina Profile or write to [email protected] or reach out on Telegram.
Manuel began working with Ethereum in 2016. He was a Lead Solidity Engineer at Centrifuge, where he designed and built smart contracts that hold a TVL of over $250 million and enabled the first RWAs on MakerDAO
Manuel worked over the years with multiple security companies as a client (Trail of Bits, DappHub, Least Authority, Code4Arena) and got more and more interested into security himself. He is currently serving as an Independent Security Researcher (LSR) at Spearbit, previously at Oak Security.
In the last two years, Manuel reviewed more than +20 codebases and found critical bugs across multiple DeFi protocols and in addition helped to improve their overall design.
Manuel also actively contributes to projects like Radicle Drips a highly optimized streaming protocol for open source dependency funding where he was involved in the design and nowadays, mostely serve as PR reviewer.
