Describe a time when applying SOLID principles improved your project.?

In a recent project, we had a monolithic service class handling multiple responsibilities,

making it hard to maintain and extend. By applying Single Responsibility Principle (SRP),

we split the class into focused services, each with a clear purpose. This drastically improved

readability, reduced bugs, and made it easier to add new features without risking

regressions. The project became more testable because each small class could be unit

tested independently.
