Backend Bootcamp 2025: Python, Flask, REST API, Docker, SQL

This course teaches you SQL 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 protectingwebsites and backend systems. You'll also learn how to monitor 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.
