At Case New Holland, I delivered complex geospatial visualizations in Power BI, combining icons and polygons on map layers and developing custom visualizations with WKT, MULTIPOLYGON, and H3 indexing. I also implemented advanced mapping techniques for location intelligence.

Across BI roles, I’ve developed dashboards, data marts, and automated reporting for organizations including JM Family and PGA of America. I’ve migrated legacy reports to Power BI and Looker, built Snowflake data pipelines, and automated workflows using tools such as Power Automate, VBA, and Python.
