PROFILE

Jonathan Whitby

Worked on the HL7/fhir repository over three months, focusing on imaging data processing, quality assurance, and standards alignment within healthcare IT. Delivered features that refined imaging data mapping and improved the accuracy of imaging selection by updating code bindings to HL7 ValueSets. Addressed data integrity by implementing invariant testing and resolving QA issues, while also restructuring subsets and updating documentation to align with evolving FHIR standards. Utilized Java and XML for backend development, data modeling, and schema updates. The work enhanced interoperability, improved downstream data quality, and ensured that imaging components remained consistent with current healthcare interoperability requirements.
