Sydney Chen enhanced data quality for Omnilore-DB/USC-Fall-2024 by developing a backend feature that filters product listings to display only current SKUs. Using TypeScript and leveraging database management skills, Sydney implemented an is_current-based filter within the product query, ensuring outdated entries are excluded from live listings. This targeted change improved the relevance of inventory data and streamlined the user experience by presenting accurate product availability and pricing. The update, tracked in a dedicated commit for traceability, also facilitated more efficient downstream analytics by maintaining cleaner datasets. Sydney’s work focused on precise, maintainable backend improvements over a one-month period.
