Professional summary
Final-year Statistics & Computer Science graduate who turns messy data into clear decisions using Python, R and SQL. Comfortable across the workflow — exploratory analysis in pandas, hypothesis testing, machine-learning models in scikit-learn, and crisp data visualization in Tableau. Analytically curious and rigorous about statistics, demonstrated across a forecasting capstone, a churn-prediction project and a Kaggle medal.

- Built a churn-prediction model in scikit-learn (gradient boosting) reaching 0.88 ROC-AUC, flagging at-risk accounts 3 weeks earlier than the existing rules engine.
- Automated a weekly KPI pipeline in Python + SQL that replaced a manual spreadsheet, saving the analytics team ~6 hours/week.
- Ran an A/B test on two onboarding emails (n = 18k), establishing statistical significance (p = 0.013) and a 9% lift in activation.
- Designed 4 Tableau dashboards for the growth team, cutting recurring ad-hoc data requests roughly 40%.
Featured projects
Time-series forecasting system for a mid-size grocery chain, built as the degree capstone.
- Engineered features from 3 years of sales data in pandas and benchmarked SARIMA against gradient-boosted trees, cutting forecast MAPE from 19% to 11%.
- Shipped an interactive Tableau dashboard so category managers could explore forecasts by store and SKU.
Imbalanced-classification study on a public payments dataset.
- Handled severe class imbalance with SMOTE and cost-sensitive learning, lifting recall on fraud cases to 0.91 at fixed precision.
- Documented the statistical evaluation (precision-recall, calibration) in a reproducible R Markdown report.
