About this course
Writing code that works is only the first step; writing code that can adapt to changing requirements is what defines a professional developer. If you have ever struggled with messy codebases, rigid architectures, or difficulty adding new features, mastering design patterns is your next step. This text-only course guides you through the essential structural, creational, and behavioral design patterns used in modern software development. You will learn to identify common architectural problems and solve them using time-tested blueprints. What you'll learn: Understand the foundational principles of object-oriented design, including SOLID principles and composition over inheritance; Implement key Creational patterns like Singleton, Factory, and Builder to manage object creation cleanly; Apply Structural patterns such as Adapter, Decorator, and Facade to organize relationships between classes; Utilize Behavioral patterns like Observer, Strategy, and State to manage communication between objects; Recognize common anti-patterns and learn how to refactor legacy code into clean designs; Explore how modern features like dependency injection and type safety simplify pattern implementation.
