Design clear service boundaries by analyzing module cohesion, ownership rules, and explicit contracts between components. This approach isolates state, defines bounded contexts, and ensures resilient module structures for growing backends without tangling dependencies.

Review software architecture for coupling issues by assessing persistence leaks, unclear dependencies, and failure containment gaps. This technology-agnostic analysis identifies whether services, packages, or domains should be split, merged, or redesigned around explicit contracts.

Assess module splitting or merging by evaluating dependency structures, state isolation, and ownership boundaries. This analysis provides principles for explicit contracts and scalable module structures to determine optimal service decomposition and package organization.

You need explicit contracts and state isolation when designing modular systems requires clear communication paths and failure containment. This prevents tangled architectures by ensuring technology-agnostic boundaries and resilient ownership rules between components.

This modular design approach applies directly to package organization and service decomposition by defining cohesive bounded contexts, public contracts, and isolation strategies. It evaluates module boundaries, ownership, and dependencies for new or existing systems.

Tangled dependencies and unclear ownership arise from lacking explicit module boundaries, public contracts, and state isolation. Applying modular design principles analyzes these boundaries and communication paths to resolve persistence leaks and failure containment gaps.
