E-Commerce Backend Development with Layered Architecture and PostgreSQL

Structuring modern web applications requires a solid grasp of backend principles, clear architectural boundaries, and robust data persistence. This text-based course guides you through designing and implementing a functional e-commerce API using industry-standard software design patterns. You will gain a clear understanding of backend organization, database integration, and application security. You will start with core backend terminology, client-server fundamentals, and HTTP request lifecycles before building application components. Through structured written lessons and code snippets, you will learn how to isolate business logic from presentation layers and data storage mechanisms. What you'll learn: - Understand foundational backend concepts, RESTful API conventions, and database principles - Design a clean layered architecture separating presentation, business logic, and persistence layers - Model application data and manage database transactions using PostgreSQL - Implement user authentication and role-based authorization flows - Build structured API endpoints for catalog management, user accounts, and ordering workflows - Apply modern configuration management and basic containerized environment setups The course opens with essential definitions and architectural patterns before moving into practical code implementations step by step. Designed for beginner developers and students with basic programming knowledge, no prior backend architecture experience is required.
