Over two months, contributed to the Hyubbbb/Daily_SQL repository by developing six SQL-driven features and resolving one bug, focusing on data extraction, reporting, and analytics. Leveraged advanced SQL techniques such as Common Table Expressions, LEFT JOINs, and recursive queries to improve query performance, data correctness, and maintainability. Enhanced business logic by implementing appointment date filtering, truck rental fee calculations with discount handling, and efficient user analytics. Addressed reporting needs with hourly data coverage and category-based price analysis, while optimizing frontend data aggregation using bitmasking. Demonstrated strong skills in SQL, database management, and data analysis to deliver robust, reliable backend solutions.

Apr 1, 2026Hyubbbb/Daily_SQL — 2026-04 monthly summary: Delivered three key items across backend SQL and frontend data handling. 1) Reporting enhancements: added max price per food category using ROW_NUMBER and complete hourly animal records by generating a 24-hour range with a recursive CTE and LEFT JOIN (commits dca25068742e89161ed29adbbc8eac0e7ef8c258; 8f6fcdbb87669dc69c55300a2ec161f27e918f88). 2) Sales Calculation Bug Fix: corrected total_sales to SUM(quantity * price) (commit dd3df0a0f64b4fed59e6056a5eda157b027e0228). 3) Front-End Skill Codes Aggregation Optimization: aggregated multiple Front End skill codes into a single bitmask using SUM(code) for efficient comparisons (commit 2f75a5ffe5659542f0300baf708fa5173b87f4ba). Overall impact: increased reporting reliability and performance, accurate revenue metrics, and streamlined frontend data handling. Technologies/skills demonstrated: SQL optimization (ROW_NUMBER, recursive CTE, LEFT JOIN), data modeling for hourly coverage, and frontend bitmask aggregation; cross-team collaboration demonstrated through clean commit messages.
