Backend Development with FastAPI: Building Scalable APIs

Modern web applications require fast, reliable, and easy-to-maintain backends. FastAPI has emerged as a premier Python framework for building high-performance APIs with minimal boilerplate. This text-based course guides you from the fundamental principles of API design to intermediate backend development concepts. You will read clear explanations, study modern code patterns, and learn how to structure real-world applications using industry-standard practices. What you'll learn: Understand foundational backend architecture and the core mechanics of the FastAPI framework; Implement asynchronous request handling using Python's async/await and type hints; Validate and serialize data efficiently using Pydantic schemas; Manage database connections and perform CRUD operations with modern ORMs; Secure your API endpoints with dependency injection and authentication protocols; Write structured unit tests with pytest to ensure code reliability. The course starts with essential terminology and basic routing before progressing to database integration, authentication, and testing strategies. It is designed for developers who know basic Python and want to transition into backend engineering with no prior API development experience required.
