Healthcare Interoperability: HL7, FHIR, and Integration Engines

Clinical systems do not speak the same language by default, and someone has to make them. Healthcare interoperability is a durable, in-demand engineering niche with a low barrier to practice. This cursus builds it from the ground up: the interoperability problem and the HL7 v2 message model that still carries most hospital traffic, then FHIR's modern resource and REST API model, and finally the integration engine, Mirth Connect, that routes and transforms clinical data between systems, plus the concrete skills to break in.
