I'm a detail-oriented senior data analyst with several years of experience working with larger datasets. I have also worked on many machine learning projects using ensemble regressors, support vector machines, K-nearest neighbors, and many other techniques.
I have proven experience using SQL, Python, Microsoft Excel, Tableau, and Microsoft Power BI for data analysis and machine learning. At, Numerator, I use SQL to manage a database with millions of records updated daily.
I graduated from Bowling Green State University with a Bachelor of Science in Business Administration specializing in economics and business analytics with a minor in history.
