Introduction to Firebase

This is a complete, architecturally-focused guide to Firebase. You will master every layer of the Firebase ecosystem — from Firestore data modeling and Security Rules to Authentication, Realtime Database, Cloud Functions, Storage, Hosting, and production CI/CD pipelines. Every module is grounded in how Firebase actually works under the hood.

• • Secure multi-user applications with Firestore Security Rules
• • Real-time collaborative features with Realtime Database
• • Serverless backend logic with Cloud Functions
• • Production React + Firebase apps with full type safety
• • Automated CI/CD pipelines with Firebase CLI and GitHub Actions

20 deep-dive theory modules organized into 5 progressive checkpoints — from Firebase foundations through production scaling. Each checkpoint includes hands-on labs that validate your skills before unlocking the next tier.
