As a Data Operations & Data Entry Specialist on client projects, I processed and cleaned high-volume datasets, maintaining 99%+ data accuracy. I built Excel and Google Sheets reporting summaries and checked records for field mismatches before system uploads.

In my Excel revenue analysis project, I cleaned transaction data, standardized product names, and analyzed regional performance. I’ve also queried business datasets with SQL and created Power BI dashboards to track KPIs and operational trends.
