Polished UI/UX featuring custom animations, intuitive interactions, and a consistent design language.
Firebase Realtime Database for live match updates.
Custom round-robin scheduling algorithm for dynamic court allocation.
Managed complex data lifecycles with multiple persistence layers (CoreData, Room, Firebase).
