Android Mobile App Build

I’m looking for a developer who can take my idea and turn it into a polished Android application. This is a software-development-focused job, so I’ll rely on your knowledge of Kotlin/Java, Android Studio, and the latest Material Design guidelines to create a fast, stable, and user-friendly app...
