Write an Android application

Hello, We need an experienced mobile developer that will create our IOS/android app. Our service is pay as you go software service. So the routine will be really simple. -A user installs the app (an account must be created for them automatically based on some unique identifier) -They select destination -They upload a file -The system gives them a quote via our API -If they have balance already taht will be used if not they will add balance in their account via an inapp purchase (for IOS) or by braintree processing (for Android) -the system will contact our server via the API to provide the service. -A callback will notify of the result. If successful then the amount remaines billed, if not then the amount is returned to the user balance. Features needed - Basic UI, possible a sketch UI kit provided if needed. - File management ( the API accepts a specific file type (.pdf) so we need to allow the user to get that filetype from dropbox, google drive + for IOS we have an app from [login to view URL] on swift to use the camera and convert to .pdf, that can be merged to be used as the way to use the camera too) - User managemenent + balance tracking. - History for success/failures - Info + support inquiries SDK's needed -Google analytics -Facebook -Appsflyer After initial development we will need you to stay on board for updates and fixes. The role afterwards will be a few hours per month or week as needed The core server is in Laravel so experience in that is a PLUS Post the keyword "APIapps" in order to be considered. We want to see some samples of IOS / Android apps you developed as weill as UI's. Your experience with API's and servers and user management is a must too, display that in your application We need to move fairly fast so the job should be starting in the next 7-10 days, the IOS app at least needs to be done within a month.
