Cover image for Should you always double down
Should you always double down on your #1 market? 🌍 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 Moving from 5 scattered CSVs to a centralized SQL-backed dashboard allowed us to see a $9.32M revenue stream clearly for the first time.

Cover image for This project was designed to
This project was designed to empower the marketing team of a retail store with actionable insights into customer behavior. By cleaning and transforming a complex dataset using Python and Pandas, I created a streamlined CSV source that feeds into a Power BI dashboard. This tool allows stakeholders to analyze spending habits, demographic trends, and channel performance to make more informed marketing decisions.

Cover image for Behind every great dashboard is
Behind every great dashboard is a clean query. I’m currently using SQL to transform raw event logs into actionable intelligence for an e-commerce build. 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. Moving from "gut feelings" to real-time data in Power BI, Tableau, and Looker Studio.
