PROFILE

Bas Van Den Heuvel

Worked on the HL7/fhir repository to deliver enhancements to the Bulk Data API, enabling client-controlled NDJSON file sizing through new parameters and exposing filesize metadata for improved data governance. Applied API design and technical writing skills to update asynchronous bundle documentation, clarifying requirements, providing examples, and refining HTML structure for better interoperability. Addressed merge conflicts in the spelling dictionary to maintain project vocabulary consistency. Improved metadata presentation by updating the Metadata Types page title and correcting work group associations, reducing routing errors. Utilized XML, JSON, and HTML to ensure documentation accuracy and support developer onboarding across evolving FHIR API features.
