Build RESTful API for Social Network with Express.js and MongoDB

In this hands-on Express.js project, we’ll build the backend API for DevConnector, a portfolio builder platform for developers. Users can register, log in, create profiles, and manage projects. Each project includes GitHub links, tech stacks, screenshots, and can receive likes and comments from other users.

We’ll implement real-world backend features such as user authentication using JWT, protected routes, file uploads with Multer, and role-based access control (RBAC). We’ll also apply validation and sanitization, use middleware for error handling and logging, and structure our API using clean, modular conventions.

This project focuses entirely on the backend. We’ll interact with a prebuilt frontend and expose all necessary RESTful endpoints, mimicking a production-level developer tool.
