🛠️ Built core features in my Library Management System:

->Seat booking with seat change support

->Shift add / remove / update

->Member management (update / delete)

On the performance side:

->Used AbortController to cancel stale API calls and avoid race conditions

->Added caching for frequent queries like seat availability

->Applied React Query for safe mutations with optimistic updates + rollbacks

->These improved both reliability and responsiveness of the system.

-> role-based allocation admin panel ,notification system
