Nov 2024 - Feb 2026

Collected and cleaned data from 6 source systems (50,000+ records), writing SQL to extract, join, and validate it before it reached any report. Developed and maintained 3 Power BI dashboards and recurring daily, weekly, and monthly reports tracking KPIs for operations, finance, and business teams across 4 departments. Automated 8 repetitive reporting and data preparation tasks in Python and SQL, cutting manual effort roughly 60% and making output consistent regardless of who ran it. Investigated recurring data discrepancies affecting accuracy and consistency, traced 12 to root cause, and coordinated with the owning teams to fix them at source rather than correcting reports each cycle. Translated stakeholder requirements into structured analysis and documented datasets, definitions, and report logic so work stayed maintainable.
