With almost 2 years of experience in blockchain development, my expertise lies in both smart contract development and security audits. I am well-versed in several ERC standards, DeFi and layer 2 protocols, and NFT projects. Additionally, I have experience with EVM opcodes and low-level assembly. My experience also includes developing decentralized applications such as NFT marketplaces and decentralized exchanges, using NextJS and React as front-end frameworks.

I am currently working as a freelancer for Sentnl.io as a Solidity Security Auditor and at Fractio Inc. as a Solidity Security Engineer, where I am responsible for ensuring the security and integrity of smart contracts through conducting security audits and providing recommendations for improvements. I have also gained expertise in identifying and addressing security vulnerabilities and gas optimizations through participating in smart contract bug bounty contests on platforms such as Code4rena and Sherlock. Additionally, I have a background in writing technical articles on the Ethereum blockchain, including Solidity wargames solutions and gas optimizations and I find myself currently developing a fully on-chain implementation of a board game, to be deployed in the near future.
