Building Robust Software: Core Principles Every Developer Should Follow
Creating high-quality software isn’t just about solving today’s problem—it’s about building systems that are maintainable, scalable, and resilient . Over the years, the software engineering community has embraced several guiding principles that help developers produce reliable and sustainable code. This article explores the core principles that every developer should know and apply. 1. SOLID Design Principles The SOLID principles form the foundation of object-oriented programming: S – Single Responsibility: Every class or module should have a single, clear purpose. O – Open/Closed: Entities should be open for extension but closed for modification. L – Liskov Substitution: Subtypes should be usable in place of their base types. I – Interface Segregation: Keep interfaces focused and minimal. D – Dependency Inversion: Depend on abstractions, not concrete implementations. Implementing SOLID ensures your code is flexible, extensible, and easier to maintain . 2. DRY (Do...
