About Ari

I am a trainer and consultant who specializes in R. I have helped companies and government agencies train their workforces and complete custom projects.

Prior to creating my own business I worked as a software engineer and data analyst at several tech companies in San Francisco.  I discovered R while working on a project to analyze real estate data. I couldn't find a package that did exactly what I needed, so I created it myself. That package is called choroplethr, and is now one of the most popular R packages for mapping open datasets. 

Please contact me if you would If you are interested working together.
