Smart Contract Auditor

I’m 29 years old and currently focused exclusively on Solidity development across all EVM-compatible Layer 2 and sidechain blockchains. I can develop, test, and deploy smart contracts efficiently using Foundry and other professional tools. Since 2017, I’ve been deeply involved in blockchain technology and smart contract security. Professionally active since 2021, I’ve participated in major auditing platforms like Code4rena and Codehawks, where I’ve reported multiple medium and high-severity findings. I was also part of the zkSync audit research team, where my contributions were recognized with a notable bounty reward — a significant milestone in my auditing journey. I’m deeply learning Chainlink and it’s crucial services in order to master RWAs, CCIP, Functions, Data Feeds (for synthetic assets), Automation and others.
