Android App with backend as Cloud Firestore

Want an Android App developed with Backend to store data in Google Firebase Cloud Firestore. The app is to make visible the members of a political party according to their location (Constituency, Sub-district and District) and their responsibilities in the party. The first signin should be authenticated by the mobile OTP facilitated by firebase, and the OTP is asked at every signout/sigin or new mobile changes. The usual closing and opening of the app should not ask for OTP (sort of preauthenticated as long as the user did not signoff ... like anyother app ) The app model sample design is all in the attached presentation file ... and the key data information (except the members) in the excel file ... * Members will register in to the app through their mobile phone. * Every member registered will be visible according to their respective district / subdistrict horizontal scroller list. * Every member unvalidated (from the backend admin console by admin) will be marked with a small red dot, after validation it will be marked as green dot (ref ppt) * There will be a seperate tab for Top level members, who will be entered manually by the admin at the backend, this list be seperately visible (2nd tab in the design) * There will be a backend admin console page, where in all the data including the members, district, subdistricts, responsibilities ... and all the data of the database will be managed (edited, deleted, added ... ) * The app will be dymanic using the data from the database, there will be no hardcoding of any data whatsoever in the program. Further queries any will be asked by the Freelancer, and no presumption, and will have to agreed and clarified before the project start. There will be no revision of the budget at a later point in the project. The project is a very urgent project and to be done in shortest timeframe possible. This is very small project and hence bid your costing accordingly.
