Intro

Hello, my name is Thomas Nestico, and welcome to my Baseball Analytics and Visualizations Website, TJStats! I am a Civil Engineer by trade, but I have a passion for data analytics and machine learning, specifically with respect to sports. This site and all of my visualizations were created using Python and its vast array of packages. The framework for this site and all of the apps is Shiny Python¹. All sources of data are referenced on each visualization.
