1 - SOLID Principles: 5 Rules for Clean Code and Flexible Software Architecture | CLEAN CODE Series

Welcome to our Clean Code Series! In this episode, we’re diving into one of the most important foundations of software craftsmanship—the SOLID principles.

If you've ever worked on a project that became harder to change over time—where one tiny edit breaks everything—you already know why good architecture matters.

The SOLID principles are a set of five design guidelines that make your code easier to understand, extend, and maintain.

What does each letter of SOLID stand for?

S — Single Responsibility
O — Open/Closed
L — Liskov Substitution
I — Interface Segregation
D — Dependency Inversion

Each principle solves a real-world problem developers face —from avoiding code duplication to designing flexible systems that can grow without chaos. By understanding SOLID, you'll start seeing patterns everywhere that make software scalable and reliable.

➡️ What's next? In the next episode, we’ll explore the first principle: Single Responsibility—what it means, and how to spot when your code is doing too much.
