Cross-Platform Music Streaming App

I’m looking to build a lean, cross-platform music-streaming app that works smoothly on iOS, Android, and the web. The goal is to get a minimal yet solid release into the stores and browser as quickly as possible.

Scope
• Core playback engine that streams tracks from our existing backend (REST/JSON).
• Secure user accounts with email or social login.
• Social sharing as the signature feature: users can share the currently playing track to their social feeds and copy a sharable link.
• Clean, modern UI that feels native on each platform.

Out of scope for this phase are offline listening and advanced playlist tools; we can revisit those once the core experience is live.

Tech notes
I’m open to React Native, Flutter, or fully native Swift/Kotlin plus a small Vue/React web client—use whatever lets you ship fast without sacrificing quality. Code should be well-structured, documented, and pushed to a private Git repo.

Deliverables
1. Universal app builds (iOS, Android) and a deploy-ready web version.
2. Source code with clear instructions to reproduce the builds.
3. A brief hand-off guide outlining key modules and any third-party services used.

If you’ve shipped similar streaming or social media features before, I’d love to see a short demo link or screenshots.
