About Me

BS-Software Engineering
Solidity Development Smart Contract Auditing DeFi Protocols

I am a dedicated Solidity developer and auditor with a passion for building the foundational layers of Web3.

My expertise lies in architecting, developing, and rigorously testing secure smart contracts for decentralized applications (dApps), with a proven track record in DeFi protocols, Automated Market Makers (AMMs), and NFT collections.

My development process is rooted in a deep understanding of the Ethereum Virtual Machine (EVM) and blockchain fundamentals, ensuring that the code I write is not only functional but also gas-optimized and secure. I complement my core blockchain skills with full-stack capabilities in React.js and Node.js, allowing me to contribute across the entire dApp development lifecycle.

Beyond development, I am highly skilled in smart contract testing and security auditing. I methodically analyze code to identify vulnerabilities, generate detailed audit reports, and provide actionable recommendations to fortify projects against threats. My work is backed by professional certifications from industry leaders like Cyfrin Updraft and SpeedRunEthereum.
