Learn three essential software design principles in this 12-minute video that can significantly improve your code quality. Master the Single Responsibility Principle (SRP), which ensures each class has only one reason to change, the Open/Closed Principle (OCP) that allows extending functionality without modifying existing code, and the Dependency Inversion Principle (DIP) which helps create more flexible and maintainable systems through proper abstraction. The video includes practical examples of each principle and explains how they contribute to better software architecture and reduced technical debt.
