Feature Engineering
Causal Inference
Polars
- Corrected selection bias in the scoring model, by building a feature engineering and causal inference pipeline in Python and Polars that integrated 11 source systems into a unified 30 million customer dataset.
- Scored the rejected-applicant population at 0.86 held-out AUC, by training gradient-boosted models within a Double Machine Learning framework to correct the selection bias in approved-only training data.
- Expanded the approvable population by 15% at flat expected default, by handing corrected scores to credit policy.

Data Science Intern Generative AI & Personalization
Julius Baer · New York, NY
Agentic LangGraph
LLM-as-a-Judge
RAG
- Replaced the analyst-and-copywriter handoff for client-facing investment documents, by engineering an agentic LangGraph system retrieving client holdings, stated preferences, and live market news into a single generated draft.
- Automated compliance review at 86% agreement with human reviewers, by building an LLM-as-a-judge critic that scored each draft against the firm's rubric and regenerated failures until they passed.
- Cut content selection time for relationship managers by 35%, by shipping the pipeline as a chat interface with human-in-the-loop revision, letting RMs iterate on a living client document.
- Surfaced a 25% engagement lift, using exploratory analysis on customer data in Python and SQL against matched controls.

Data Scientist Co-op Customer Acquisition
Ask2AI · New York, NY
Uplift Modeling
DiD
Mixed-Integer Optimization
- Improved cross-channel ROI attribution by 22% and identified optimal credit limit thresholds, by building uplift models and difference-in-differences designs that isolated incremental campaign impact from last-touch bias.
- Lifted customer LTV 12% and cut churn 25%, by pairing uplift modeling with mixed-integer optimization to reallocate acquisition budget across channels.

Data Scientist Capstone Customer Analytics & Segmentation
TD Bank · New York, NY
Customer Analytics
Fraud Detection
XGBoost
- Raised fraud model precision-recall AUC from 0.20 to 0.67, by training XGBoost with SHAP on 100 million transactions.
- Validated fraud-detection strategy for senior leadership, by quantifying incremental catch rate against a holdout.
- Shaped segmentation and anti-money-laundering strategy, by clustering customers on transaction behavior and delivering automated reporting on the resulting risk tiers.
