An interview with Booz Allen Hamilton Data Scientist, Nicholas Kallfa

Last weekend I had a sit-down conversation with Nicholas Kallfa. Nicholas is a data scientist at Booz Allen Hamilton where he works on creating tailored products for government clients using R and mathematical computing techniques to visualize information in R’s open-source platform Shiny. Not only is Nicholas a great communicator of advanced mathematics, but he shared with us the various methods he uses to guide clients through difficult concepts to reach a mutual understanding. This interview was quite enjoyable since there were an abundance of cats knocking things over in the background. If there is residual noise, I blame it on them.

Toolkit: R (R Studio), Python (Spyder), Git/GitHub, Postgres, Microsoft SQL Server, QGIS, Latex, Tableau, Excel

Nick’s favorite online resources:

  • Udemy (mostly to learn something completely new for the first time)
  • Stack Overflow
  • Relevant subreddits
  • Mostly just google and see where he ends up

Influential books about data:
