Analytics Portfolio – Projects & Case Studies

Built a comprehensive customer segmentation model using Python and machine learning to identify high-value customer groups. Developed targeted marketing strategies that increased campaign ROI by focusing on the most profitable segments.

Created an interactive Power BI dashboard analyzing customer purchase patterns, lifetime value, and churn risk. Integrated data from multiple sources using SQL to provide a unified view of customer behavior.

Designed and executed A/B tests for marketing campaigns and website optimization. Applied statistical methods to ensure valid results and actionable recommendations for business decisions.

Built a free, privacy-first web app that takes small businesses from a raw customer or sales export to labeled customer segments — entirely on their own computer. Handles data cleaning, feature engineering, exploratory analysis, and automatic segmentation, so non-technical owners can find their VIPs, at-risk, and growth segments without sharing data with anyone.
