Security Researcher, Decentralization nerd, zk enthusiast!

Biography

I started my career as a Web2 solution-oriented builder, helping over 20 startups build their products and scale beyond MVP. Over the years, I've transitioned from full-stack and DevOps roles to Architect roles before moving to Web3 in 2019. Initially, I worked mostly with BTC and their UTXO model before transitioning into the EVM ecosystem.

In 2020, I fell in love with DeFi and began helping projects build their products by adopting a "secure by design" methodology. Throughout 2020, I was active in the white-hacking community, and after participating in several confidential white-hacking operations, I developed a passion for security and started offering my expertise as a security researcher to various projects.

In 2021, I joined EthernautDAO's council with the goal of bringing more developers into Web3. Leveraging my accumulated knowledge, I aimed to effectively onboard new Web3 developers.

I have also been an active Smart Contract developer, assisting various confidential protocols in building their smart contract architecture. I emphasize the importance of creating the right architecture by combining both Web2 and Web3 components.

In 2022, I joined the Spearbit crew as a Security Researcher after Devconnect Amsterdam. There, I worked alongside my colleagues to help projects release their products safely.

In my spare time, I started Soldeer, the first Solidity-centric package manager built in Rust currently integrated into foundry.

Private Engagements

While the engagements listed here are primarily through Spearbit/Cantina, I have also privately participated in over 100 security reviews. These can be discussed in detail upon request.
