Backend development (also stylized as back-end or back end development) is the skill that powers the web. Yet it does it modestly, without fanfare—allowing people to browse their favorite sites without even knowing about all the work put in by the backend developer or team.
Backend development languages handle the ‘behind-the-scenes’ functionality of web applications. It’s code that connects the web to a database, manages user connections, and powers the web application itself. Backend development works in tandem with the front end to deliver the final product to the end user.
Back-end developers primarily develop and maintain the core functional logic and operations of a software application or information system. Typically, a back-end developer has expert programming skills in C++, C#, PHP, Node.js and other high-level programming languages.
The key job role of a back-end developer is to ensure that the data or services requested by the front-end system or software are delivered through programmatic means. Back-end developers also create and maintain the entire back-end of a system, which consists of the core application logic, databases, data and application integration, API and other back-end processes. Moreover, a back-end developer performs the testing and debugging of any back-end application or system.
