Audit portfolio

Smart contract security researcher and EVM developer specializing in DeFi protocol security, vulnerability research, and secure smart contract development.

Ranked #24 on Code4rena over the past year, with extensive experience auditing production-grade DeFi protocols through competitive security reviews on platforms including Code4rena, Sherlock, Cantina, and Immunefi.

Experienced in identifying high-impact vulnerabilities across complex DeFi systems, including economic exploits, access control issues, oracle manipulation, reentrancy vulnerabilities, accounting flaws, and protocol design weaknesses.

Beyond security research, I have hands-on Web3 engineering experience, having built and shipped multiple decentralized applications, DeFi tools, and blockchain infrastructure projects through hackathons and independent development.
