GoF Design Patterns and SOLID Principles for Developers

Writing clean, scalable code requires a solid grasp of object-oriented design fundamentals. This course guides you through core SOLID principles and classic Gang of Four (GoF) design patterns to help you build flexible software and navigate technical architecture interviews with confidence. You will learn to structure maintainable systems, refactor rigid code, and articulate architectural choices clearly. What you'll learn: - Understand core SOLID principles to design resilient object-oriented software - Implement creational patterns like Singleton, Factory Method, and Builder - Apply structural patterns such as Adapter, Decorator, and Facade to connect flexible components - Utilize behavioral patterns including Strategy, Observer, and Command for efficient object communication - Integrate modern decoupling techniques and dependency injection concepts - Solve software architecture challenges and prepare for common technical interview questions. You will start with foundational definitions, core object-oriented principles, and clean code terminology. Through detailed written explanations and code snippets, you will analyze each pattern's structure, trade-offs, and practical application. This beginner-friendly course is designed for aspiring software engineers, junior developers, and candidates preparing for technical interviews. No prior architecture experience is required.
