Backend Developer vs Full Stack Developer: What's the difference?
A Backend Developer and a Full Stack Developer are often confused but differ in focus. A backend developer builds the server-side logic, databases and APIs that power an application behind the scenes. A full stack developer builds both the front end and the back end of an application, owning a feature from the user interface down to the database. Below we compare what each does, the skills they share, typical experience and pay, and which path to choose.
