About Me
Work & Impact
I am a Data Scientist with experience developing customer segmentations, modeling behavioral patterns such as loyalty, price sensitivity, churn, and relative product quality using embeddings, as well as consulting for in-store tests through causal inference. I also build and maintain scalable ETL pipelines in Python, SQL, and Spark to support enterprise data products and high-traffic dashboards, ensuring reliable, production-grade insights.
Methodology & Mindset
I take a comprehensive approach to problem solving, combining statistical rigor with real-world practicality. My focus is on turning data into insights that support better decisions, streamline processes, and make complex challenges easier to manage.
My Story
I grew up just north of Indianapolis and earned a BA in Economics and an MS in Applied Economics from the University of Cincinnati. Outside of work, I stay active through Brazilian jiu-jitsu and mountain biking. I now live in Nashville with my wife and our two dogs.
