About
I’m a recent graduate from Oregon State University with a B.S. in Applied and Computational Mathematics and a minor in Computer Science. My work blends data engineering and analytics: collecting and cleaning complex data, validating data quality, and building clear dashboards that drive decisions. I’ve developed pipelines in SQL and Python, built predictive models in Python, implemented numerical solvers in MATLAB, and created interactive dashboards in Power BI and Tableau. I enjoy solving open-ended problems and building tools that make data easier to understand and use.
