Aymen Ben Belkacem developed and enhanced healthcare data interoperability features across the Nictiz/HL7-mappings and Nictiz-R4-zib2020 repositories, focusing on structured data exchange using FHIR and HL7 standards. He delivered new XML Schema Definitions and expanded ADA and FHIR-based data mappings, enabling support for evolving healthcare data models and seamless cross-system integration. Using Java, Python, and XML, Aymen implemented foundational instance support, updated data validation logic, and introduced new FHIR resource types to improve data quality and maintainability. His work addressed complex data modeling and integration challenges, resulting in robust, standards-compliant solutions for healthcare interoperability without major defect reports.

March 2025: Delivered FHIR Compatibility and Data Validation Enhancements for Nictiz/Nictiz-R4-zib2020.
