Backend Developers are professionals who focus on the server side of web applications. They work with databases, server logic, and application programming interfaces (APIs) to ensure that everything functions smoothly behind the scenes. Their primary goal is to create a robust and efficient system that supports the user interface and handles data processing. These developers typically use programming languages like Python, Java, or Ruby to build the server-side components. They also manage server configurations and optimize performance to ensure that applications run efficiently. Overall, Backend Developers play a crucial role in making web applications reliable and scalable.
