While building this Executive Revenue dashboard, the data told a different story. Instead of pouring more into the US market, we identified a massive opportunity to make countries 2-4 (India, UK, and Brazil) more competitive.
The Tech Stack:
ETL: Pandas (Python)
Database: MySQL
Viz: Power BI

Key Metrics Extracted:
Traffic Quality: Identifying high-intent sources via avg_session_duration.
Campaign ROI: Using expected_uplift to pinpoint winning customer segments.
Behavioral Trends: Mapping friction points in the checkout funnel.
