About

Background

I'm finishing a Master of Business Analytics at Bentley University while working in software. My undergrad was CS at Elon, with minors in Data Science and Statistics. I was also inducted into Mu Sigma Rho, the national statistics honor society.

Most recently I was a contract developer at Integrated Computer Solutions building IoT data pipelines for medical devices. Before that I spent two years at Blue Cross Blue Shield of Massachusetts as a full-stack engineer, where most of my work was around API performance, SQL optimization, and CI/CD.

I'm drawn to work at the intersection of engineering and analytics: building systems that not only run well, but generate insight.
