Over five months, A. Koo enhanced healthcare data interoperability and integrity across the Nictiz/Nictiz-R4-zib2020 and Nictiz/HL7-mappings repositories. Koo delivered modular FHIR data models, expanded HL7 mappings, and enforced database constraints to improve data quality and standards alignment. Using Java, Python, and SQL, Koo addressed missing data mappings, clarified documentation, and integrated new health concepts such as ToiletTrainednessFeces into existing pipelines. The work included refactoring LivingSituation profiles for NL-core conformance and strengthening schema relationships, resulting in more maintainable, standards-compliant systems. Koo’s contributions demonstrated depth in backend development, data modeling, and healthcare interoperability standards implementation.

March 2025: Delivered ZIBFHIR LivingSituation Data Model Improvements and NL-core Alignment for the Nictiz/Nictiz-R4-zib2020 repository. The work modularized the LivingSituation data model into hasMember profiles, added NL-core profiles for conformance, documented and constrained deviations for HomeAdaption and LivingCondition, and fixed NL-core override/resource ID issues to enhance data accuracy and standards alignment. These changes reduce maintenance burden and improve interoperability with NL Core-compliant systems.

December 2024: Delivered four ADA/FHIR data representation updates and expanded HL7 mappings in Nictiz/HL7-mappings to improve interoperability and data quality across ZIB contexts (AbilityToEat, AbilityToDressOneself, AbilityToDrink). These changes regenerate and introduce ADA/FHIR instances aligned with the latest specifications, providing a stable foundation for broader data exchange. No major bugs were reported or fixed this month; stability gains come from data-model alignment and expanded mappings. Technologies demonstrated include HL7 FHIR, ADA/FHIR mappings, data modeling, and commit-based traceability.
