React & Ethereum Full-Stack Engineer

I’m putting together a new Ethereum-based product and need a senior engineer who can own the entire stack. Your main canvas will be React on the frontend, while the core logic lives on Ethereum smart contracts and an API layer that ties everything together.

Here’s what I expect you to handle:
• Frontend development – build an intuitive React interface that talks seamlessly to the blockchain.
• Backend development – design and code the server side (Node.js or your preferred JS runtime) so it can process transactions, manage data, and expose clean endpoints.
• API integration – connect external services and on-chain data through well-structured REST or GraphQL APIs.

Solidity experience is a must for the smart-contract work; familiarity with Ethers.js or Web3.js will make integration smoother. You should be confident writing tests, handling security best practices, and deploying to mainnet or testnets.

Deliverables will include the smart-contract source and deployments, a production-ready React app, the backend/API codebase, and concise documentation so the team can extend or audit your work.

If you’ve shipped full-stack Ethereum apps before and enjoy taking products from idea to launch, let’s talk about the details and timeline.
