Who is a Backend developer?

A Backend Developer is a programming specialist who focuses on developing and maintaining the server-side of web applications or other software systems. They are responsible for creating and supporting the application’s logic, interacting with databases, handling client requests, and ensuring the security and scalability of the server infrastructure. Backend developers work with various technologies and tools, including programming languages (such as Python, Java, C#), frameworks (such as Django, Spring, ASP.NET), databases (such as MySQL, PostgreSQL, MongoDB), and interaction protocols (such as HTTP, WebSocket). Their work is aimed at ensuring the stable and efficient operation of the application’s server-side, enabling users to interact with web applications or other systems through the user interface.
