## Profile Information

Short Bio
My work includes data mining and running predictive analytics on the data. I use Tableau, R and MSI to chart and plot data over the course of time to identify trends and issues with our customer data. We have hundreds of millions of data rows I comb through in Netezza and Teradata databases. With R, I utilize the qcc framework to build control charts that quickly and precisely identifies violations, and helps us figure out what we need to focus on to ensure high quality customer data. I have also built Control Chart functionality in Tableau. I predominately use Tableau to visualize the data I work with.
