Android App Prototype Developement

I am seeking an eligible developer to build a high-fidelity prototype for an Android app using Kotlin, Java and Jetpack Compose. Key features I anticipate in the app include:

- Writing unit tests to validate the code for ensuring smooth app functionality.

The developer must work on a predefined design, fully functional prototype reflecting the actual app. I am interested in developers who have experience in Android development particularly with Kotlin, Java, and Jetpack Compose. Knowledge of unit testing is necessary.
