Nicholas Kallfa 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 was an abundance of cats knocking things over in the background. If there is residual noise, I blame it on them.
