I offer specialized data cleaning and preparation services, ensuring that even the most complex datasets—like the 3 million data points I processed for a drone delivery company—are accurate, consistent, and ready for analysis. My expertise in advanced Excel formulas, Power Query, SQL, and Python allows me to efficiently tackle messy data, transforming it into a reliable foundation for insightful analytics
