About Me

I'm a Business Analyst and 2025 graduate of the University of Wisconsin–Madison, with a degree in Information Science and a Certificate in Data Science.

I specialize in building ETL pipelines, designing BI dashboards, and automating data workflows that scale — translating complex business needs into reliable data models that teams can trust.

Outside of work, I enjoy playing tennis and doing yoga. I'm always open to new opportunities — feel free to reach out!
