I built this e-commerce analytics

I built this e-commerce analytics case to demonstrate how data can move beyond dashboard reporting into business diagnosis and executive decision support.

The workflow covers the full analytical process:

• data acquisition and preparation • data modeling and KPI design • exploratory analysis • mobile vs desktop conversion diagnosis • cross-device recovery analysis • revenue leakage estimation • Tableau visualization • executive PowerPoint storytelling

The goal was to show how analytics can identify friction, quantify business impact, and translate findings into clear recommendations.

Tools used: Python, SQL, Tableau, and PowerPoint.

Turning data into insight, and insight into business action.
