The back end of a website is the code & infrastructure that powers the application , and is responsible for everything that happens on the server side:
- Data storage and organization: The back end stores and organizes data for the application
- Communication: The back end communicates with the front end to send and receive information
- Performance: The back end ensures the website performs correctly
Back-end developers work on the server-side software, focusing on: Databases, Back-end logic, Application programming interface (APIs), Architecture, and Servers.
Back-end development is more technical than front-end development, but the two teams work closely together.
Some popular back-end languages include: JavaScript, Python, Java, C++, and PHP.
Back-end developers should have skills in:
- Version control systems, like Git
- Server management
- Communication
- Time management
- Cloud computing and hosting
