About:

I am a security researcher primarily focused on Web3 contracts with Solana/Solidity/Vyper/Rust codebases.

In 2023, I graduated with a master's degree in Computer Science, specializing in machine learning and data science. My thesis focused on finding smart contract vulnerabilities with deep learning, which redirected my career path to web3 security.

I have over two years of experience auditing codebases in Solidity, Rust, and Vyper. I've consistently ranked at the top of the HatsFinance leaderboard and have served as a lead auditor and judge multiple times. In addition, I've conducted several private audits and testing.

Full-time Solana auditor at Accretion Labs since May 2025.
