system-architect

Clean architecture enforces separation of concerns, ensuring that domain logic remains isolated from infrastructure details. This maintains codebase independence and promotes clear interfaces, which is critical for long-term maintainability and efficient development.

You need Domain-Driven Design when structuring complex software systems, as it aligns technical implementation with business requirements. It enforces robust domain modeling and clear boundaries to handle structural complexity and ensure maintainability.

To optimize performance in system design, analyze structural dependencies to identify bottlenecks and implement caching strategies alongside asynchronous processing. This ensures your architecture supports future scalability requirements and maintains robust performance.

The best way to plan a microservice refactor is to review the proposed design against clean architecture principles and SOLID guidelines. This ensures the new structure adheres to best practices for future growth and ease of maintenance.

You should avoid clean architecture when a project's scope is too small to justify the abstraction overhead. Over-engineering with strict SOLID principles and domain-driven boundaries can introduce unnecessary complexity for simple, short-term scripts.
