Full-Stack React Node Development

I need a modern web application built from the ground up with a React.js front-end, a Node.js + Express.js back-end, and MongoDB as the data store. You’ll architect the entire stack, set up routing, state management, RESTful (or GraphQL if you prefer) APIs, and connect everything seamlessly...
