kgrzybek/sample-dotnet-core-cqrs-api

This system is an e-commerce platform that manages customers, products, and orders with support for multi-currency pricing and foreign exchange conversion. It enforces business rules through a domain-driven design, utilizing typed identifiers, aggregates, and a structured event notification system for eventual consistency. The architecture separates concerns across API, application, domain, and infrastructure layers, incorporating features like email notifications, in-memory caching, and an outbox pattern for reliable message processing.
