Worked on the lblod/app-organization-portal repository, focusing on data enrichment and quality improvements for address and municipality records. Designed and implemented a ProvincesConceptScheme to link addresses to province URIs, using RDF and SPARQL for data modeling and migration. Managed the full migration lifecycle, including rollback procedures to ensure data integrity after an accidental push. Developed SPARQL migrations for deduplicating triples across shared and administrative unit graphs, and introduced a CLI tool to restart migrations. Emphasized code hygiene, documentation, and changelog updates, supporting maintainability and standardized data management practices across the platform while aligning with business requirements for data consistency.

May 1, 2025For 2025-05, delivered groundwork for province data enrichment in lblod/app-organization-portal, including designing a ProvincesConceptScheme and architecture to link addresses to province URIs. Implemented two migrations to add province URIs to addresses and create the provinces concept scheme. However, due to an accidental push, those migrations were rolled back to restore the pre-change data state, and rollback procedures were validated. The work demonstrates risk-aware change management and sets up a robust path for future re-implementation with proper governance and QA gates.
