Data professional who analyzed Adidas sales with Python and Excel and built interactive Power BI dashboards to show trends and performance.

I analyzed Adidas sales data with Python to identify sales patterns, seasonal trends, and product performance. I used Excel pivot tables to validate the analysis and built interactive Power BI dashboards covering sales growth, regional revenue, and category performance.

At Webmatterz, I cleaned datasets in Excel and Python, prepared reports and Power BI dashboards, and assisted with testing the Ekperi language app before launch. I’ve also worked on a housing price prediction project using Scikit-learn, Pandas, NumPy, Matplotlib, and Seaborn.
