General Principles

DRY — Don't Repeat Yourself

Each piece of logic has one authoritative location. Extract duplication only when it is real, not coincidental.

YAGNI — You Aren't Gonna Need It

Build only what the current requirement demands. Do not speculate about future needs.

KISS — Keep It Simple, Stupid

Choose the simplest solution that works. When two approaches are equivalent, prefer the one that is easier to read.

SOLID

Single Responsibility
