Clean Architecture separates domain entities and business logic from framework and infrastructure concerns, keeping your core code independent and testable. Define clear use cases, establish bounded contexts from Domain-Driven Design, and organize layers so business rules remain unaffected by technology choices.

Follow Clean Architecture and Domain-Driven Design principles: enforce separation of concerns, use early return and minimal nesting, decompose into reusable modules, and apply clear naming conventions. These practices catch anti-patterns early and reduce costly refactoring.

Organize layers to isolate business logic from infrastructure, define bounded contexts for domain boundaries, apply library-first problem solving to reuse proven solutions, and enforce consistent naming conventions. This ensures your microservice remains maintainable and adaptable as requirements evolve.

Library-first development prioritizes existing, proven solutions over custom implementations, significantly reducing development time and maintenance burden. This approach leverages vetted code and community support, allowing you to focus on domain-specific logic.

Domain-specific naming patterns aligned with Clean Architecture and Domain-Driven Design create consistency across your codebase. Clear, intent-revealing names for entities, use cases, and boundaries reduce confusion and make business logic immediately understandable.

Implement error handling at appropriate architectural layers, keeping business logic isolated from infrastructure-level exceptions. Use early return patterns and minimal nesting to make error paths explicit and maintainable across your system.
