Full-Stack Web3 & Smart Contract Engineer

Freelancing Career

Mar 2023 - Present • 3 yrs 4 mos

As an independent Full-Stack Web3 & Smart Contract Engineer, I specialize in the end-to-end architecture, development, and deployment of decentralized applications (dApps). Operating as an independent freelance contractor, I develop secure on-chain logic and seamless user interfaces for Web3 applications and clients, ensuring high performance, minimal gas costs, and rigorous security standards. Core Responsibilities & Engineering Achievements: Smart Contract Architecture: Designed, tested, and deployed secure Solidity smart contracts for custom token ecosystems (ERC-20, ERC-721, ERC-1155), decentralized payment routing, and automated multi-sig escrow vaults. Security & Optimization: Conducted rigorous testing using Hardhat and Foundry. Implemented OpenZeppelin security primitives (ReentrancyGuard, Ownable) and optimized EVM storage access patterns to significantly reduce transaction gas fees for end-users. Frontend Web3 Integration: Built highly responsive, state-driven frontend dashboards using React.js, Next.js, and Tailwind CSS to translate complex blockchain data into clean user interfaces. Wallet & Provider Connection: Engineered seamless user authentication and wallet connection flows using Wagmi, Viem, and Ethers.js, supporting MetaMask, Coinbase Wallet, and WalletConnect protocols. Backend System Design: Developed robust Node.js backends and webhook listeners to track live on-chain smart contract events and sync them with off-chain PostgreSQL databases (Supabase), ensuring real-time UI updates. Cryptographic Authorization: Implemented EIP-712 typed data signing, allowing users to securely validate and authorize recurring transactions off-chain before broadcasting to the network. Core Tech Stack Utilized: Solidity | React.js | Next.js | Node.js | Hardhat | Foundry | Wagmi | Viem | Ethers.js | Tailwind CSS | PostgreSQL | OpenZeppelin
