We are seeking a skilled MERN stack developer to extend our existing Node.js/Express backend by building a dedicated, interactive Client Panel for our furniture inventory management system. The project requires developing a responsive React.js front-end with a state management solution (like Redux or Context API) for the client-facing interface, which must include features like user authentication (JWT), a filterable product catalog with real-time stock levels fetched from our existing MongoDB database, detailed product pages, and a client dashboard for tracking inquiries. The backend must be robustly built with Node.js & Express.js, creating secure RESTful APIs (or GraphQL endpoints) for all client interactions, ensuring proper data segregation and protection. Expertise in integrating React with Node.js/Express backends, managing MongoDB schemas for user and product data, and implementing JWT-based authentication is essential. The final deliverable must be a fully integrated, tested, and documented module that seamlessly connects with our current system. Please share your portfolio of similar MERN stack projects along with your proposal.
