devmentors/ddd-building-a-model

This system is a domain-driven design (DDD) exploration framework that implements an e-commerce checkout workflow. It manages the lifecycle of placing orders, including cart management, payment processing, and order validation. The codebase demonstrates various DDD patterns—such as specialized aggregates, the specification pattern for business rules, and logic fragmentation—across multiple versioned project structures. It enforces specific business constraints, such as quarterly purchase limits and payment method restrictions based on customer type.

devmentors/ddd-building-a-model was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point the surveyor at a repository you know and see whether you agree with it.
