📌 * Python, Machine Learning, Clustering (K-Means), Feature Engineering, Exploratory Data Analysis*

Developed a customer segmentation model to identify distinct user groups based on behavioral and transactional patterns.

Applied clustering techniques (K-Means) combined with feature engineering to uncover meaningful segments, enabling more targeted marketing, improved personalization, and efficient budget allocation.

The project follows an end-to-end analytics workflow — from data preprocessing and exploratory analysis to model development and insight generation — with a strong focus on translating data into actionable business decisions.
