Problems This Solves

!

Building a custom backend from scratch is too expensive and time-consuming for your MVP timeline.

!

Your application needs real-time data updates (like chat, live scores, or collaborative editing) but your stack cannot support it.

!

User authentication setup (Google, Apple, email/password) is complex and full of security edge cases.

!

Push notification delivery is inconsistent and you have no centralized system to manage messaging campaigns.

Methodology

Our Proven Process

1

Firebase Project Architecture

We design Firestore collection schemas, plan security rules, and configure Firebase project settings.

2

Firestore Database Setup

We structure NoSQL documents, write composite indexes, and implement real-time snapshot listeners.

3

Cloud Functions Backend

We write serverless TypeScript functions for API endpoints, triggers, and scheduled background tasks.

4

Auth & Push Notifications

We configure Firebase Authentication providers and set up FCM push notification campaigns.

5

Security Rules & Deployment

We write Firestore security rules, run emulator tests, and deploy to Firebase Hosting.

Frequently Asked Questions

Firebase is Google's Backend-as-a-Service (BaaS) platform. It provides a NoSQL database (Firestore), user authentication, serverless functions, file storage, and push notifications — all without managing servers, letting you focus entirely on your application.
Firebase uses a NoSQL document database (Firestore), while Supabase uses PostgreSQL (relational SQL). Firebase excels at real-time sync and mobile apps. Supabase is better for complex relational queries and SQL-native teams.
Firestore uses snapshot listeners that push data changes to connected clients instantly. When a document updates on the server, every subscribed client receives the new data in under 100ms without polling.
Yes, when configured properly. We write comprehensive Firestore security rules that validate user authentication, check custom claims, and restrict document access per user role — preventing unauthorized reads and writes.
