Aug 2009 - Present • 16 yrs 9 mos

As a Web3 Full-Stack Engineer, I design, build, and deploy production-ready decentralized applications and blockchain infrastructure. My experience covers the entire Web3 stack: - Smart Contract Development: Built and audited Solidity contracts for DeFi protocols, NFT marketplaces, multi-sig wallets, and on-chain payment systems using Foundry and Hardhat. - Frontend & Backend Development: Developed high-performance DApp frontends with Next.js/React, and built scalable backend services with Node.js and Go, integrating wallet connections, on-chain data, and off-chain APIs. - Web3 Infrastructure: Implemented non-custodial MPC wallets, on-chain payment gateways (including Coinbase x402), and account abstraction solutions, ensuring security and user experience. - DevOps & Deployment: Set up CI/CD pipelines, Docker containers, and cloud deployment workflows for reliable, high-availability applications. - End-to-End Project Delivery: Led multiple projects from requirements gathering and architecture design to testing, deployment, and post-launch maintenance, with a focus on security, scalability, and clean code. I prioritize best practices, gas optimization, and user-centric design to deliver secure, performant, and maintainable Web3 solutions.
