Experience
Data Scientist
Feb 2023 — Present · New York, NY, US
As a Data Scientist at S&P Global, I developed and operationalized machine learning models to drive retention and revenue growth. Using Python with scikit-learn and XGBoost, I built a churn prediction model that boosted annual net retention by 4.2 percentage points, reversing a negative trend. I also redesigned the company\'s SaaS pricing strategy and authored its implementation in Power BI, enabling 150+ sales reps, which ultimately accelerated revenue growth by 35.3% year-over-year. Additionally, I led the migration of analytics development to a data warehouse (Google BigQuery). By designing a multi-layered data model, I enabled fellow analysts to create advanced reporting using SQL and Python.
