Boris de Vloed worked on backend data quality and integrity initiatives for the lblod/app-organization-portal repository over a two-month period. He delivered a SPARQL-based production data cleanup, removing incorrect BetrokkenLokaleBesturen data and test-kerk-nijlen records to restore data integrity and improve analytics reliability. In a subsequent effort, Boris implemented a database migration to remove deprecated 'Gemeente' and 'Provincie' classifications from the administrative unit graph, further reducing data duplication. His work involved writing SPARQL migration scripts, updating documentation in Markdown, and maintaining a clear audit trail through version-controlled commits, demonstrating a methodical approach to database management and migration.
January 2025: Backend data-quality initiative for lblod/app-organization-portal. Implemented Administrative Unit Classification Cleanup by removing deprecated 'Gemeente' and 'Provincie' classifications from the administrative unit graph using a SPARQL migration script (OP-3393). Updated documentation and changelog to reflect the backend data structure cleanup. Commits recorded for traceability: 8e311c6bab95113f3a266fda173cdcc8d436295c, 3cd6c2c7f7c67f30db29187bbc367bcd921e1c3d.

December 2024: Delivered and validated production data cleanup via SPARQL migrations in the lblod/app-organization-portal project. Implemented two SPARQL migration files to clean up incorrect production data, specifically removing BetrokkenLokaleBesturen data related to Nieuwerkerken and all data associated with test-kerk-nijlen, to restore data integrity and improve downstream reporting. These changes reduce data noise and strengthen governance for analytics and user-facing features. All changes are tracked in version control with commit 925289a9dc597abab9c75137772eab7b1a645af1.
