John is the Chief Data Scientist for MailChimp.com. He's also a recovering management consultant who's done a lot of analytics work for large businesses (Coke, Royal Caribbean, Intercontinental Hotels) and the government.
These days John does all sorts of awesome data science for MailChimp, and blogs for fun about analytics through narrative fiction at Analytics Made Skeezy. Spoiler alert: the characters who do meth are frequently confused or in peril. John does not do meth.
