iPhone & Android - PhoneGap Application

We are looking for building a PhoneGap application (iOS & Android) with a short timeframe using PhoneGap (front end) and Google Firebase platform (backend server for storage, notifications, analytics etc.). App designs are almost ready (wireframes, screens, app flows etc.) and we need someone to be able to connect the front end to the backend. App Flow: 1. User installs the app and then selects a bunch of outcomes which results in fetching an audio file then streamed to the user. First few times streaming is free, thereafter the users would be asked for in app purchases. List of the Audio recordings would be made available at a later stage but currently dummy files can be used for the app and in future audio files (following a naming convention) would be replaced on Google Firebase storage. 2. Users would have access to a menu (designed in UI) which lists out premium features that can be used once or twice for free later available for multi use after in app purchase. 5. One of the app features (paid) needs business logic to be built: there would be different alphabets on the screen, when the user clicks on the alphabets, based on the logic (we would provide you the logic) a sequence would be formed. Each time the sequence would match from a list of available sequences to present a given result. 4. Advertising monetisation (google apps integration). Please get in touch.
