Breaking Tight Coupling: How Dependency Inversion Transforms Kotlin Applications

Tightly coupled code creates fragility—when requirements change, small modifications trigger a domino effect of failures throughout the system. Dependency Inversion Principle is essential for building systems that are testable, scalable, and maintainable, enabling teams to swap implementations (like payment providers) without rewriting core business logic. Understanding this principle is foundational for modern software architecture and directly impacts development velocity, code quality, and system resilience.
