In this talk, I will explore how implementing SOLID principles can transform your code architecture into a more scalable, maintainable, and flexible system. We’ll break down each principle—Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion—and provide practical examples to demonstrate how adhering to these guidelines leads to cleaner, more robust code. Key points: Definition and benefits of SOLID principles Practical examples for each principle Best practices for applying SOLID in modern software architecture
