I’m an independent developer building a personal web3 project and need an experienced full-stack engineer to help me build specific modules. This is not an agency or company project — I’m the sole owner and decision-maker.
What You’ll Build:
React Frontend Module Connect wallet (MetaMask/WalletConnect) Display token balances + switch chains (Ethereum, Polygon) Simple UI for token swap simulation (no real funds — mock data only) Smart Contract Module (Solidity + Rust) Write a basic AMM-style swap contract (Solidity) Write a simple cross-chain message handler (Rust — Polkadot/Substrate) Add unit tests using Hardhat
Backend API Module (Node.js) Build REST endpoint to fetch mock user transaction history Store mock data in JSON (no database needed)
Must-Have Skills: Built at least 1 live React + blockchain project (share GitHub or demo link) Experience with Solidity + EVM chains (Ethereum/Polygon) Experience with Rust + Polkadot/Substrate (must show proof) Can write clean, tested, documented code
Nice-to-Have: Experience with Jotai, Golang, or IPFS UI/UX sense for web3 apps
Timeline: Duration: 4–6 weeks (part-time, ~20 hrs/week) Flexible hours — async communication preferred Timezone: Any — but must respond within 24 hrs
Do NOT Apply If: You’ve never shipped a live React + blockchain project You don’t have Rust + Polkadot experience You need constant supervision You can’t deliver clean, tested code
