Less Greedy Code, Less Misery: The Power of SRP Through a Battle-Tested Lens

Most critical production bugs don't come from bad algorithms—they come from cramming too many responsibilities into one place. This is a deep dive into the Single Responsibility Principle (SRP) from a pragmatic, real-world perspective: how the "convenience trap" breeds God Objects, why a typical order-processing function becomes a maintenance landmine, and how a Senior refactors it into clean, testable layers. Clean architecture isn't free—but when your project scales to 100 features, it's the very thing that keeps it from collapsing.
