Platform
Mobile App Developer
Mobile app developers write smartphone apps for both the Android and iOS platforms, using native Java/ObjectiveC/Swift or hybrid approaches, such as React Native. This role requires knowledge of OOP, mobile application design and a sense of beauty as smartphone app developers often communicate with designers. The ability to use efficient algorithms and data structures is also important as smartphones have limited resources.
