PROFILE
Steven Van Der Vegt
Steven van der Vegt contributed to the nuts-foundation/nuts-knooppunt repository by delivering four features over four months, focusing on system architecture, local development, and data privacy. He created comprehensive C4 architecture diagrams using Structurizr and Markdown to clarify system interactions and support onboarding. Steven set up a reproducible local development environment with Docker Compose, integrating a HAPI FHIR server and PostgreSQL to streamline testing and contributor setup. He enhanced architectural visualization for addressing functionality and implemented BSN pseudonymization in Java, introducing Docker-based interceptors for secure data handling. His work demonstrated depth in backend development, configuration management, and security-focused engineering.

Oct 1, 2025October 2025: Delivered pseudonymization support for NVI integration in the HAPI FHIR server within nuts-knooppunt. Implemented BSN pseudonymization for storage and audience-specific retrieval, introduced a new Docker image for the pseudonymization interceptor, and updated Docker Compose to deploy it. Added necessary Java interceptors to wire the flow into the HAPI pipeline. Commit reference dd16a67b939cd97be233bb01522907ce7c1031c8 (Adds pseudonym support for NVI to HAPI (#154)).
