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.

Security researcher specializing in blockchain smart contracts since 2023, with experience auditing Solidity, Rust, and Vyper codebases. 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.
