 ## Overview
 This project uses the **Stack Overflow Annual Developer Survey 2025** (49,123 responses, 170 features) to predict a software developer's annual salary. The pipeline covers end-to-end data science: exploratory analysis, feature engineering, unsupervised clustering, regression, and multi-class classification.
