Data analyst using Power BI and Excel to turn sales, health, and water-quality data into clear insights.

My sales, health, road accident, and water-quality projects have given me hands-on experience analyzing data and presenting patterns through visualizations. I’ve created interactive Power BI dashboards for sales analysis and visual dashboards showing heart-disease data trends and possible risk patterns.

For water-quality analysis, I assessed freshwater indicators to identify seasonal trends and pollution sources. I also analyzed road accident data to examine casualty patterns by vehicle type, road surface, and location.

As a Data Visualization Associate in the Early Remote Internship at Excelerate, I completed a program focused on data visualization. I work with Power BI and advanced Excel, and have working knowledge of SQL and Python for data preparation and analysis.
