ChatTrade — C#/.NET Chat and Integration Prototype

Development prototype for real-time chat and customer-service workflows. The C#/.NET codebase separates Domain, Application and Infrastructure layers, with REST APIs, public and admin MVC interfaces, PostgreSQL, EF Core and Dapper. It includes SignalR/JWT examples, transaction commit/rollback examples and adapters for WhatsApp and voice providers. Docker Compose supports local setup. Several integrations default to mock mode. This entry presents the prototype architecture; the source repository remains private. The cover is an architecture overview, not a screenshot of a production deployment.
