Bring updates to a react-native android application

We want to make changes to this Android app which has been made using React-native. It works as a third-party API-based app to Spotify, its functionality is to use Spotify’s API and automatically make playlists for the user. Its back-end is an ML model which makes Spotify API calls and then delivers the result to the front end of the app. The backend is hosted on a HEROKU server. You must have proper knowledge and experience in the field of APIs and hosting backend. We will provide you with the source code.

The changes are as follows:

UI/UX
• Screens and button designs (will be provided by the client)
• Text and fonts

Feature Updates
• Add two new options in the app which is related to the ML backend (will be explained)
• Making a change in the playlist API

Server Update
• Rehost the application’s backend in HEROKU production server

Bugs and Error fixing
• Fixing a Google login error
• Some other minor In-app bugs (will be explained)
