Responsibilities of a Mobile App Developer

Every mobile development project starts off with an idea. The first task of a mobile developer is to understand this idea and what the client is trying to achieve with the application. This allows the mobile developer to determine what the implementation should look like

The App Developer is then responsible for the technical feasibility and how to comply with the guidelines of the app store operators. A developer basically implements the wishes of customers’ mobile applications. They consult with function designers, UX designers, UI designers, and other programmers.

They also check whether the front end and back end of the app are correctly linked. Another task is to further develop concepts of existing apps. But it doesn’t end here. It is also part of the job profile to create a detailed time and cost estimate for a potential project.
