To design a microservice with hexagonal architecture and Domain-Driven Design, define bounded contexts, isolate domain logic from infrastructure using ports and adapters, and enforce SOLID principles. This approach ensures your core business rules remain decoupled from external frameworks.

Refactoring code to improve clean code involves analyzing existing structures for architectural smells, extracting domain logic into isolated layers, and applying appropriate design patterns. This process resolves structural degradation and aligns the implementation with SOLID principles.

Yes, you can review your backend design before implementation by evaluating proposed changes against architectural boundaries and hexagonal principles. This validates structural soundness, verifies dependency direction, and ensures the design adheres to clean code standards.

You need to apply SOLID principles and design patterns when structuring new backend systems or resolving complex architectural challenges. These patterns guide dependency inversion and boundary definition, preventing tightly coupled code and ensuring long-term maintainability.

Your monolithic backend architecture struggles with testing and scaling because tightly coupled components prevent isolated test execution and boundary enforcement. Applying hexagonal architecture and DDD separates domain logic from infrastructure, resolving these structural bottlenecks.
