What I'm looking for

I want to apply ML-driven risk analytics to prevent fraud, improve model performance in production, and build decision-support tooling. I’m excited to work cross-functionally, use causal and experimental methods, and ship scalable automation.

I’m a data science professional with 2.5+ years at American Express, where I work at the intersection of risk analytics, model implementation, and decision support. I diagnose production model gaps using segmented analysis, PSI monitoring, and data quality reporting to deliver timely corrective actions.

I build and operationalize machine learning and automated detection pipelines to improve capture on emerging fraud themes. From feature engineering and XGBoost/logistic regression to end-to-end pipeline delivery, I’ve improved model capture by 30% and contributed to projected annual revenue loss prevention of $20M+—while also supporting global decision workflows with a custom GPT for a 500+ member team.

I also strengthen risk processes through proactive frameworks and performance tracking, including revamped proactive limit increase logic and automated monthly/quarterly MIS decks for leadership benchmarking. I’ve partnered cross-functionally on a $155M+ international product launch and mentored team members to raise onboarding and execution quality.
