APIs

Bad data breaks good code. You’ve written Python that works perfectly in testing, only to watch it fail in production because of a malformed API request, a messy CSV, or a missing config value. That’s the hidden cost of Python’s flexibility: without runtime validation, you’re always one bad input away from a crash. Enter Pydantic. This book takes you from the foundations of data validation to real-world applications in APIs, data pipelines, configurations, and machine learning workflows. Along the way, you’ll explore practical techniques, advanced features, and alternatives like Marshmallow, attrs, and dataclasses, so you’ll always know which tool is right for the job. If you’re a Python developer, data engineer, or FastAPI user, this is your roadmap to writing safer, cleaner, and more reliable code.

Your API deserves more than just working, it deserves to be exceptional. read more...

I'll teach you to craft strong APIs with FastAPI, use Pydantic and SQLAlchemy for data integrity, and apply patterns that avoid repetition. As we go through CRUD operations, advanced pagination, filtering, and bulk data handling, you'll see that each concept builds on what came before. You'll learn to add features and connect them into a smooth whole. You'll find step-by-step instructions for secure authentication, password resets, role-based permissions, and even two-factor authentication. When we talk about user experience, I show you to implement dynamic forms, drag-and-drop uploads, custom error pages, and theme toggles. You'll learn to bring external services into your app, like sending emails, integrating SMS, or allowing users to log in with Google or GitHub.
