Problems we solved
Role Isolation
Three distinct user types (Customer, Vendor, Admin) each need completely separate layouts, permissions, and data access.
State Persistence
Cart, wishlist, and auth state must persist across page refreshes without a backend round-trip.
Vendor Analytics
Vendors needed real-time financial dashboards, inventory tracking, and order processing - all in one view.
How we built it
Redux Toolkit multi-slice architecture with localStorage persistence, role-based routing, and Recharts analytics.

7 Redux Toolkit slices with custom localStorage middleware for instant state restoration

- 4
Separate login/register portals per role with JWT token auth
