Developed a microservice-based Government Invoice Integration system connecting CRM, Government Invoice Service, Tax Portal, and a Middleware layer. Services communicate asynchronously via RabbitMQ and synchronously via REST APIs. The Middleware acts as the central hub orchestrating data flow between internal CRM data, government e-invoice submission, and tax portal validation. Built with .NET Core and Clean Architecture principles.
