I'm a data scientist at Booz Allen. My team works in cyber security, and I tend to focus on operationalizing models; taking things from "it works on my machine" to broadly deployable services. I also happen to be a functional programming hobbyist.
I have a lot of JavaScript things here on my SO profile. That's largely from my history in web development; it used to be my main gig. I try to keep tabs in case I ever need to bundle anything into a web app.
