Mobile Developer

Job description

The client is building mobile apps (iOS and Android) that communicate with a server via an API. Most parts of the system are already build: backend and API, frontend of both apps, API client code in both apps. What's missing is the wiring between the app frontends and API layer.

The client is preferably looking for a mobile developer with knowledge in both iOS (Objective-C) and Java, but only one of those would be possible as well.
The developer should have experience working with Dagger 2 and EventBus or similar technologies, asynchronous/reactive apps and preferably J2ObjC.

Development time is estimated to be 10-15 days. If possible, the freelancer should sit at the client's office at the Factory (Rheinsberger Str. 76/77).
