Full-Stack Developer for EVM DApp

JavaScript, Node.js, React.js, Blockchain, Full Stack Development, Solidity, Smart Contracts, DApps, Cryptocurrency · I already have an MVP running on a standard EVM stack—Solidity contracts, a React.js interface, and a small Node/Express backend—but it needs a seasoned full-stack blockchain developer to turn it into a production-ready dApp.

What you’ll walk into • An existing GitHub repo with a functional proof-of-concept. • React is baked in (the chosen framework); designs are still coming together, so some screens will arrive progressively. • Solidity contracts compile and deploy, but they still need a proper security pass, gas-cost tuning, and upgradeability considerations. • Only WalletConnect is required for the first release, yet the codebase should remain flexible enough to add MetaMask or Coinbase Wallet later.

First milestones • Finalise and harden the Solidity contracts, add a complete test suite, and create clean deployment scripts. • Wire up WalletConnect in the React client, ensuring seamless connection, signature, and network-switching flows. • Extend the Node/Express layer to expose any missing endpoints and protect sensitive contract interactions. • Spin up a subgraph or lightweight custom indexer so the frontend can pull on-chain data efficiently.
