Android developer

I would like to build a medical prototype in Android native with kotlin. There will be a patient app and a doctor app.
- The patient is able to send a series of content combined between Images, Text with images or just text, local mp3 file from his device, or a playlist from Spotify.
- The series of content will be received in a single stream that can be swiped manually or auto swipe, for example, if the patient sends IMAGE1, TEXT, MUSIC, Youtube video. When the doctor opens the app stream category, will see these streams one by one either swiped manually or automatically, so it will be an image then text, a music player then a youtube player playing the youtube url.
The doctor can send also a stream of content to one patient or select multiple patients to send once.
For each time there's a received stream, the user should be notified with Firebase notification.
In the "see stream section" you could find one stream or multiple ordered by received date, you can select which stream you want to read. as i said the reading mode is similar to a gallery, page by page swiped manually or automatically.

Requirement:
- Firebase notification
- Native android dev with kotlin
- Use of MVVM
- Rest api hosted in Firebase host
- Storage in firebase
- Patient and doctor authentication in Firebase Auth
