1. 01Build a complete backend project

   Discover what happens behind every web page and understand the role of servers, backend applications, databases, APIs, and business logic.

2. 02Module 2 — HTTP & Web Communication

   Learn how browsers and servers communicate through HTTP. Explore requests, responses, methods, status codes, headers, and JSON.

3. 03Module 3 — Your First Server

   Build your first backend server and understand routing, requests, responses, middleware, and the basic architecture of a backend application.

4. 04Module 4 — Building REST APIs

   Learn how to design and develop RESTful APIs that allow different applications and services to communicate with each other.

5. 05Module 5 — Databases & SQL

   Discover how applications store information. Learn relational database concepts, tables, relationships, SQL queries, and database design.

6. 06Module 6 — CRUD & Data Management

   Build real application features by creating, reading, updating, and deleting data through your backend API.

7. 07Module 7 — Authentication & Authorization

   Learn how applications identify users and control what they are allowed to access. Implement authentication, sessions or tokens, roles, and permissions.

8. 08Module 8 — Backend Architecture

   Move beyond simple applications and learn how to organize backend projects into clean, maintainable layers such as routes, controllers, services, and data-access logic.

9. 09Module 9 — Validation & Error Handling

   Learn how to validate incoming data, handle unexpected errors, return meaningful responses, and make your API more reliable.

10. 10Module 10 — Security Fundamentals

    Discover common backend security risks and learn practical techniques for protecting APIs, user accounts, sensitive data, and application infrastructure.

11. 11Module 11 — APIs, Services & Integrations

    Learn how to connect your backend to external services such as payment systems, email providers, maps, cloud services, and other APIs.

12. 12Module 12 — Testing Your Backend

    Learn how to test API endpoints and backend logic, identify bugs, and make sure your application continues to work as it evolves.

13. 13Module 13 — Git, Environment & Deployment

    Learn professional development workflows, environment variables, configuration management, and how to deploy a backend application to a production environment.

14. 14Final Project: Power a Real Application

    Build a complete backend from scratch, including a database, authentication, REST API, business logic, security measures, and deployment. Connect it to a front-end application to create a complete full-stack project.
