Designing Architecture

This one gives you a structured framework for making architecture decisions instead of just winging it. You get pattern selection guides based on team size and codebase scale, visual diagrams for common approaches like Clean Architecture and CQRS, and a decision template that forces you to document trade-offs. The feature-based vs layer-based directory structures are opinionated but sensible. What I like is the validation checklist at the end, it catches the common mistake of picking microservices for a three-person team. Best used when starting new projects or refactoring existing ones where you need to justify your choices to teammates or future you.
