What problem does it solve?
Clean Architecture helps you design software that stays maintainable, testable, and easy to change by keeping business rules isolated from frameworks, databases, and delivery mechanisms. It is especially useful when codebases start to become tangled, dependencies point the wrong way, or refactoring is blocked by tight coupling.
Core Features & Use Cases
- Dependency direction guidance: keep inner business layers independent from outer technical details.
- Domain and entity design: model real business rules, invariants, and value objects without persistence or UI concerns.
- Use case structuring: separate orchestration from business logic, define input/output ports, and keep controllers thin.
- Boundary and framework isolation: place ORM, web, logging, and external API concerns at the edges.
- Testing architecture: make each layer testable in isolation and enforce boundaries with architecture tests.
- Use case: Review a Next.js or backend repository, identify architectural violations, and produce a prioritized refactoring plan that improves separation of concerns.
Quick Start
Ask for a Clean Architecture review of a codebase or feature, and I will identify boundary violations, recommend layer changes, and summarize the highest-impact refactors first.
