In sense of roles in Software Development, if your system can be split into two parts (Frontend and Backend system), which are developed independently, you can find these two roles: Frontend and Backend Developer.
If you develop for the Frontend, then it is the client, which is used by the users, just like a Web Client developed with JavaScript and HTML. If you develop for the Backend, it is most likely the server doing all those tasks, which need to be processed centralized. An example can be a server with a database connection to store and retrieve articles for the clients. Finally these two parts need to communicate with each other.
