Independent Web3 / Blockchain Developer
OREO • ZZP
Jul 2025 - Jul 2026 • 1 yr
Independent Web3 / Blockchain Developer focused on building decentralized applications and smart contract solutions using Solidity, Ethereum, React, TypeScript, and ethers.js. I independently design and develop Web3 projects from concept to implementation, including smart contract architecture, frontend development, wallet integration, blockchain transactions, testing, and deployment to Ethereum test networks. My development work includes O-Escrow, a decentralized ETH escrow DApp built with Solidity, Hardhat, React, TypeScript, Vite, ethers.js, and MetaMask. The project demonstrates on-chain escrow creation, ETH funding, completion, cancellation, buyer authorization, and smart contract testing. I focus on building practical, maintainable Web3 applications while continuously improving my knowledge of smart contract security, blockchain architecture, decentralized application development, and modern frontend technologies.
