The HL7 Sender is a Windows-based application designed to generate and transmit HL7 messages in a controlled, repeatable way for development and integration testing. It was built to remove the friction of relying on live clinical systems when validating interfaces and workflows.

Developed using C# and .NET, the application provides structured message creation, configurable endpoints, and detailed logging of outbound traffic. Particular emphasis was placed on robustness and observability, with clear error handling and retry behaviour to support realistic testing scenarios.

This project reflects my experience working with healthcare interoperability standards and integration tooling. The focus is deliberately pragmatic: predictable behaviour, transparent logging, and tooling that supports developers and analysts during real-world interface testing rather than abstract demos.
