Managing real-time updates for song requests was a significant challenge, demanding efficient state management to ensure changes were instantly reflected across multiple connected clients. The app also needed to scale effectively, handling high volumes of concurrent users during live events without performance bottlenecks. Ensuring strong user engagement meant balancing robust functionality for DJs with simplicity for attendees, avoiding unnecessary complexity. Supporting diverse audiences required localization features such as multi-language support and cultural adaptability. Additionally, smooth onboarding was essential—streamlining login and registration while maintaining strong security for users unfamiliar with digital interfaces. Finally, implementing role-based features required carefully tailored interfaces and logic to provide seamless experiences for both DJs and attendees.
