Looking for a JavaScript Front-end and Node.js Back-end Developer on Web Application based on L2 Network

I need a developer who can own both ends of a web application that will run on top of an L2 network like Polygon, Base, Arbitrum, etc. On the front-end, the immediate priorities are a solid user-authentication flow and a responsive, data-driven dashboard that updates smoothly as new information comes in. Modern JavaScript is a must; if you are comfortable in React framework, that’s perfect—just keep the code modular, testable, and clean.

On the back-end, I’m looking for a Node Version Upgrade that pairs naturally with the front-end.

If this sounds like the sort of project you can take from zero to production-ready, let me know your timeframe and any questions after check the JD.
