🚀 IMPORTANT: Watch the Deployment Video FIRST
If Google Sign-In doesn’t work or your app breaks in production, this is why.
👉 Full Deployment Tutorial (Required): https://youtu.be/HGs-4QjyjHQ?si=DMbB2vzAomakLNE1

This is not just a website.
This is a real web application with a real backend.

In this video, you’ll learn how to build a full-stack web app where users can create accounts, log in, upload files, save data, log out, and come back later with everything still there — exactly how modern SaaS products work.

We build everything step by step using Google AI Studio (Gemini) and Firebase, so you understand the core backend system, not just one demo app.
You can reuse this exact structure for any project, any niche, any SaaS idea.

What You’ll Learn in This Tutorial
✅ User Authentication with Firebase
Email & password sign-up
Google Sign-In
Login / logout flow
Email verification for real users

✅ Storing User Data with Firestore
Save user-specific data that persists after refresh and logout
Build apps where each user only sees their own data
Secure backend logic without building everything from scratch

✅ File Uploads with Firebase Storage
Let users upload files to your web app
Files are linked to the logged-in user
Upload, display, and delete files from the UI

✅ UI Connected to a Real Backend
App reacts to authentication state
Dashboard updates with real data
Example of free plan limits (like SaaS apps)
Why This Matters
A website becomes a real web app when it has:
Users
Saved data
Persistent state
Backend logic

That’s what companies look for.
That’s what real products use.
And that’s exactly what we build here.

⚠️ Important Note
Google Sign-In requires a deployed app with an authorized domain.
If you skip deployment, authentication will not work correctly.
That’s why the Deployment Video at the top is mandatory.
