What if you could build a complete backend for your mobile app without building servers, authentication, databases and storage completely from scratch?

That’s the idea behind BaaS (Backend as a Service).

Welcome to Video 22 of AI Mobile Engineer 2026 by The Techzeen.

In this video, we build the foundation for choosing and working with a backend for our React Native applications.

What You'll Learn:
BaaS (Backend as a Service)
What BaaS is and how ready-made backend services can provide databases, authentication, storage, APIs and more.

Database Fundamentals
How applications store and manage users, products, orders, messages and other data.

SQL vs NoSQL
Tables, rows, columns and relationships vs flexible document and collection-based data models.

PostgreSQL
How relational databases work and why PostgreSQL is the database foundation behind Supabase.

Firebase
Google's backend platform, including Firestore, Realtime Database, Authentication, Storage and its broader mobile ecosystem.

Supabase
A backend platform built around PostgreSQL with Database, Authentication, Storage, Realtime and APIs.

Firebase vs Supabase
Understand the architectural differences and the factors you should consider when choosing a backend for your mobile application.

This video connects directly with our previous lessons:

REST APIs → CRUD → TanStack Query → BaaS → Backend → Authentication
