You will get a Node.js REST API integration and backend module for your web app

I will build or connect a Node.js / Express.js backend module for your web application. The project can include REST API endpoints, third party API integration, request validation, data handling, authentication related logic and connection with your React or Next.js frontend. I begin by reviewing the API documentation, required inputs and outputs, error cases and acceptance criteria so the integration is scoped around a real workflow rather than a generic API connection.
