Inventory microservice
CRUD domain with Hibernate, optimistic locking, and integration tests. Docker Compose for local parity with production-like databases.
Architecture decisions
- Hexagonal-ish dependency direction between domain services and persistence adapters.
- Repository-level integration tests against containerized MySQL.
- Centralized audit fields for created/updated metadata.
Outcomes
- Prevented negative-stock edge cases in concurrent requests.
- Kept deployment artifact lightweight and predictable for staging.
