About

I am a data scientist who has a diverse range of experience in healthcare finance, e-commerce, and industrial IoT sectors. In my spare time, I sometimes answer questions about data visualization. If my answers helped and you want to say thanks, consider buying me a coffee!

Formerly I was a professional chess player, reaching the top 200 in the United States. These days I play on lichess under the handle joddle.
