Welcome to the Software Design section. Here you will find guides, examples, and best practices to design software that is robust, maintainable, and less likely to turn into a monument to desperate refactoring.

This section covers both code design and architectural design: principles like cohesion, coupling, SOLID, and dependency injection live next to architectural patterns, DDD, and modeling techniques. The goal is not to collect buzzwords, but to understand when a design choice actually reduces the cost of change.
