Biography
I’ve been active in the blockchain space since early 2024, with a strong focus on smart contract security and open-source development. I specialize in Solidity and Cairo auditing, with additional experience in frontend development using React.
Since entering the space, I’ve audited a variety of protocols through security competitions on platforms like Cantina and Codehawks, sharpening my skills in vulnerability discovery, risk assessment, and on-chain analysis. I’ve also contributed to several open-source projects, primarily on OnlyDust, where I worked on Cairo-based applications and Web3 tooling.
