Android(JAVA), iOS (Objective-C)
A medical center require a mobile app for make the interact between the medic and patient more simple.
They need an app with 2 interfaces for differents kind of users: on for the medic and another for patient.
The app need an instant message system, an appointment manager and a couple of specific sections for each sides (Patients and professionals).
I developed the same app for iOS (swift) and Android. The backend was developed by another team.
