Emily Tanabe developed the Supply Chain Network UI for the opensupplyhub/open-supply-hub repository, focusing on enhancing data transparency and accessibility within the Production Location page sidebar. She implemented a contributors breakdown by organization type and created a drawer interface for detailed data sources, including anonymized groups for non-public contributors. Using React, Redux, and JavaScript, Emily refactored the sidebar code path to improve maintainability and clarify data flow, laying groundwork for future enhancements. Her work enables stakeholders to quickly assess contributor context and data provenance, supporting better governance and onboarding while establishing a scalable UI pattern for ongoing data-source integrations.
