Looking for Java developer for a simple validation android application

I am looking for a skilled Java developer who can help me build an Android app. The app’s main purpose is to validate data through API. I already have a clear idea of the features and functionality that I want to include in the app. However, I am open to suggestions to make the app even better. There is no specific target Android version for the app, so the developer can use their discretion. The app is going to be installed in paytm POS machine and it will send and receive payment request to the paytm app in the machine and validate data. UI design of the app is ready in figma and concept is clear. Backend api and database is also done. there might be a few addition to the backend db and api. Backend is designed in PHP Laravel.

Ideal Skills and Experience:
– Strong proficiency in Java programming language
– Experience building Android apps
– Experience with Php Laravel can be an add on
– Experience with integration with Paytm POS machine
– Familiarity with API integration – Ability to work collaboratively and communicate effectively with the client
