As a motivated Smart Contract Developer with hands-on coursework and internship experience, I bring a solid foundation in Solidity, automated testing with Hardhat, and a strong focus on secure coding practices. I’m eager to contribute clean, gas-efficient contracts and grow within a team building trustworthy decentralized applications.
With three years developing and auditing smart contracts for DeFi and NFT projects, I combine practical Solidity expertise with thorough testing and remediation experience. I’ve led integrations with front-end teams, optimized gas usage across core modules, and strengthened protocols through proactive security fixes.
As a senior Smart Contract Developer with five-plus years designing scalable, audited protocols, I’ve architected upgradeable systems, led multiple security audits, and advised on tokenomic designs and governance models. I excel at translating product goals into secure, efficient on-chain logic and mentoring engineering teams on blockchain best practices.
