Senior MERN Blockchain Frontend Completion
Budget: $100 – $120 USD
I’m looking for a senior-level full-stack developer who can take over a partially built MERN front-end and drive it to production-ready quality. The interface already covers the basic page structure, but it still needs polish, tighter component logic, and solid Web3 connectivity. You’ll be expected to refine and finish the React codebase, wire it to a fresh set of REST/GraphQL APIs you build yourself, and ensure everything works seamlessly with smart-contract calls across Ethereum, Binance Smart Chain, and Solana.
The job suits someone who has at least three years of hands-on blockchain development behind them, is comfortable spinning up Node/Express endpoints from scratch, and knows how to keep Redux (or similar state management) in sync with on-chain events. You’re free to propose improvements—whether that means upgraded authentication flows, real-time data updates, or sharper UI/UX—so long as the end result is a clean, responsive dashboard that communicates flawlessly with our contracts.
Acceptance criteria
• React components refactored and fully functional across desktop and mobile
• New APIs implemented, documented, and connected to MongoDB
• Web3 interactions tested on Ethereum, BSC, and Solana testnets
• End-to-end build passes linting, unit tests, and a final integration test suite
If you have the blockchain depth and MERN speed to deliver the above, let’s talk timelines and milestones.
