- Understand key security features such as HTTPS for encrypted communication, JWT for stateless authentication, and bcrypt for secure passwords
- Learn how to connect PostgreSQL to Grafana, visualize metrics, and set up dashboards to monitor your infrastructure
- Understand various web hosting options such as shared hosting, VPS (Virtual Private Server), dedicated hosting, and cloud hosting. Learn how each type works

Requirements
- No programming experience required — we’ll teach you everything from the ground up.

Description
This course teaches youSQL and Python for backend development, using real-world examples to help you build practical, job-ready skills. You’ll learn how to model data relationships, work with relational databases like PostgreSQL, and build fully functional REST APIs using Flask.

As you progress, you'll also explore advanced programming techniques such as concurrent and parallel programming to write faster, more efficient backend code.

We start from the basics, covering how to install and set up your development environment for both SQL and Python.

You'll write actual queries, manipulate data, connect databases to Python, and build APIs that mirror real-world applications. You’ll also learn to use Postman to test your APIs and VSCode as your coding environment.

In addition, the course will introduce essential web security techniques, including HTTPS for secure communication, JSON Web Tokens (JWT) for authentication, and bcrypt for password hashing—giving you a strong foundation in protecting

websites and backend systems.

You’ll also learn how tomonitor your PostgreSQL databases using Grafana, gaining insight into performance metrics and system health—an essential skill for maintaining and scaling production systems.

Why SQL Matters in Backend Development:

SQL (Structured Query Language) is the standard language used to interact with relational databases—one of the most critical components in any backend system.

As a backend developer, you're constantly working with data:storing it, retrieving it, securing it, and analyzing it.

SQL allows you to design efficient data models, write optimized queries, and enforce rules to ensure data accuracy and integrity.

From simple data lookups to complex joins and transactions, SQL gives you the tools to manage the backend's most valuable asset—its data.

Why This Course is Unique

This course gives youtwo essential skills in one:

SQL– to master data handling, querying, and database design.

Python– to build the backend logic, APIs, and integrations that bring your applications to life.

By learning SQL and Python together, you'll understand not onlyhowto build backend systems but alsowhyeach part matters—from data storage to API delivery.

This combination makes you a more complete, capable, and confident backend developer.

The course emphasizes clean, modular design and encourages good practices from day one. Whether you're a beginner or looking to transition into backend development, this course is structured to guide you step-by-step.

No prior backend experience required—just motivation and curiosity. Let’s get started!

Who this course is for:
- This course is suitable for people who want to become backend developers and are looking to learn Python and SQL, as well as master core skills like database management, API development, and server-side programming.
