This course provides learners with the skills to build scalable, high-performance backend applications using Node.js and Express.js. You will learn how to set up a Node.js server, build RESTful APIs, integrate databases, handle authentication, manage middleware, and deploy applications to production. By the end of the course, you will be able to design and implement a complete backend system for web and mobile applications.
