Resume Builder Dev – Fetching User & Implementing Query Client | React Query + Firebase Integration

🔥 In this session of the Resume Builder series, we implement user data fetching with React Query (TanStack) and Firebase — making authentication state and user info reactive, cached, and reliable.

✅ What you’ll learn in this video:
✔️ Installing and setting up React Query (QueryClientProvider)
✔️ Fetching the current authenticated user
✔️ Managing loading, success, and error states
✔️ Auto-syncing user data with Firebase Auth
✔️ Laying the foundation for scalable user/session handling

💡 Why This Matters:
🔹 Simplifies async data logic
🔹 Improves performance with smart caching
🔹 Keeps user experience smooth and consistent
