Build an Audio Player App with Expo (React Native)

I need a mobile application built with Expo (React Native) that includes an audio player feature. The app should allow users to:
• Play, pause, and stop audio files
• Skip forward and backward
• Adjust volume
• Play audio in the background (when screen is off or minimized)

Additional requirements:
• Clean and maintainable code
• Compatible with both Android and iOS
• Simple and user-friendly UI
• Documentation for setup and usage

Please include examples of your previous projects with audio or media features if available.
