Cross-Platform Music Playlist App

I'm looking to develop a music playlist recommendation app for both iOS and Android platforms, with integration to Spotify as the sole music source. The app's main feature will be social sharing, allowing users to share their recommendations in response to user questions.

Key Features:
- Social Sharing: Users can share playlists and recommendations.
- Spotify Integration: Pull music and playlists from Spotify.
- User-friendly Interface: Easy navigation and engaging design.

Ideal Skills & Experience:
- Experience in developing cross-platform mobile apps.
- Expertise in integrating Spotify API.
- Strong background in UI/UX design.
- Experience with social sharing features in apps.

Looking forward to your proposals!
