Design Foundations: Core Principles and Object-Oriented Patterns

By Sergey Nosov

You know SOLID. You can name the Gang of Four patterns. But when someone challenges your design decision, can you explain the trade-off-or only repeat the rule?

Principles you cannot articulate are principles you cannot apply.

79 principles. Zero hand-waving. Each follows the same rigorous format: a clear explanation, warning signs that reveal violations, and markers that confirm correct application. No "it depends" without explaining why.

Five chapters cover:

SOLID and core design principles-as trade-offs, not commandmentsComponents and dependencies-coupling, cohesion, and the forces that shape themContracts and correctness-the discipline that separates reliable code from fragile codeClarity and readability-why good code explains itselfThe complete Gang of Four catalog-when they solve problems, when they create them

Reach for this book before an interview, during a design debate, or when refactoring unfamiliar code.

Design Foundations is Book 1 of the Software Development Principles series. Language-agnostic. Framework-independent. Built to last.

Your foundations determine everything you build on top of them. Make yours unshakeable.
