Need a simple android app

I need a developer who will make me a simple app. I will provide needed API and backend data.

This is how it should work, the design will be provided after.

1. User login page: User cant register, its only able to log in using pin that is provided earlier to him. Users are stored in database which is reachable by api.
2. After successful login, there should be a home page that will only have a background which will be provided and top bar title. On the right hand side will be floating button (scan button).
- Scan button when pressed - it should enter in qr code scanner/bar code scanner, after scanning designated QR code successfully it should decode it and get an UID from it. That UID should be immediately used for API call where he gets all needed customer data (full name, e-mail, amount, status, group)
- When api responds successfully the app should show new screen with customer name on the top, amount below the name and two Buttons. One button should say (Pay with points) and other should say (Pay with money).
- Pay with points button when pressed - app shows new screen and asks user to enter amount of payment(float value) and receipt id (string value) and a submit button below. After pushing that button it should send POST request to another api endpoint ( will be provided). After successful API response, app should show Thank you message.
- Pay with money button when pressed - app shows new screen and asks user to enter receipt total (float value), percentage (int value) and receipt id (string value) and a submit button below. After pushing that button it should send POST request to another api endpoint (will be provided). After successful API response, app should show Thank you message.

At the moment that is everything what is needed in it, I will need a developer that will be ready to maintain the app later on as this is a prototype for a B2B service and we should have great number of clients.
Later on there will be expansions of app as review part, reservation part, etc..

Im open to every question and will provide all the API changes and design before we start.

Im a developer too and have started working on a Flutter app but just dont have time for it. Your past work and the price are the most important here.
