Over two months, Hyubbbb developed analytics-driven SQL features and data-layer improvements for the FLY_PCSQL repository, focusing on business needs such as pricing accuracy, sales visibility, and data quality. They engineered solutions like Seoul restaurant ranking queries, recursive CTEs for hierarchical E. coli data, and car rental pricing scripts, applying advanced SQL and database management techniques. Their work included data integrity checks, distinct value counting, and scaffolding for educational problem sets, all structured for maintainability and scalability. By combining production-ready queries with educational content, Hyubbbb demonstrated depth in SQL querying, recursive logic, and file management to support robust analytics workflows.
