Built an end-to-end used-car pricing analysis for VW and Audi listings in the UK market. The work combined exploratory analysis, data cleaning, feature engineering, and model comparison, then translated the results into a CPO pricing recommendation. It showed strong practical judgment by using Random Forest as the preferred model and explaining the business impact in terms leadership could act on.

What stood out6
- Combined VW and Audi listings correctly and used brand-aware EDA to surface the premium gap between the two marques.
- Identified and removed clearly invalid rows such as zero-engine-size and extreme price outliers before modeling.
- Compared Linear Regression and Random Forest using R², MAE, and RMSE, and reported a substantial improvement for the tree model.
- Connected model output to CPO decision-making by estimating pricing exposure and recommending a practical deployment path.
- Leakage-Free Feature Engineering
- Comparative Model Evaluation
