Hi, I'm Ari Lamstein,  

a software engineer who builds data science software.

What would you like help with?


I am best known as the author of choroplethr, a suite of open source R packages for mapping demographic statistics.


I write a blog that focuses on the intersection of software engineering and data analysis.  

About Ari

I currently work as a Staff Data Science Engineer at a consultancy that specializes in measuring marketing effectiveness. Prior to this I spent five years as an independent consultant and trainer. Within training I specialized in introductory R training. Within consulting I focused on projects that were based on choroplethr, my open source framework for mapping demographic statistics in R.

I live in San Francisco, California, and grew up on Long Island, New York.
