What needed to be solved
Turn an imperfect trip dataset into a defensible classification workflow with consistent evaluation across several models.
How the project addressed it
Prepared 1,156 records, explored trip patterns, engineered features, and evaluated four machine-learning models using accuracy and ROC-AUC.

My contribution
Built the workflow from cleaning and feature engineering through visualization, model comparison, and interpretation.
- Completed cleaning, exploratory analysis, feature engineering, and classification.
- Compared models using accuracy and ROC-AUC instead of a single metric.
- Presented the results with visualizations and a clear model-selection rationale.
What the work demonstrated
The strongest model achieved 95.2% accuracy and a 0.97 AUC score.
