TopMusic

Music streaming ecosystem · Our role: Lead Mobile Engineer (Architecture, Bug Fixing & Enhancements)

The problem

An established Christian music streaming platform needed its mobile app to keep playing reliably: continuous audio through the iOS lock screen, offline playlists, and a codebase the team could keep extending.

What we built

We joined the existing product as lead mobile engineers for architecture, bug fixing and enhancements. We rebuilt the background audio playback service, added buffering and local cache management for offline listening, and moved the app onto a cleaner TypeScript architecture with optimised Redux state stores.

Results

  • Live on iOS, Android and the web
  • 100K+ installs on Google Play (public listing band, Oct 2026; covers the whole product)
  • Background playback that continues through the iOS lock screen
  • Offline playlist caching

Install figures are public Google Play listing bands and describe the whole product, not our contribution alone.
