At first, David loved math. That turned into building cool stuff with software, mainly websites. Among the cool things David has created are the entire operational website for a successful laboratory, the whole operational website for a distributed hotel startup, the online radio player for the largest NPR radio station, content management systems for a bunch of magazines and TV shows such as Rachael Ray, Car and Driver, and Elle, and other personal projects including TrackTime.TECH.



Preferred Environment

Vim Text Editor, Sublime Text, Linux

The most amazing...

...widget I've ever built was the first online radio player for WNYC, the largest NPR radio station. Our users listened to it for about 100,000 hours a week.

I developed an app for punching the clock on projects, to-do lists, and invoices. I use it for my day-to-day productivity. The robotic demo video you can see on the homepage is the first I made with my new E2E test and demo creation library. The demo is the E2E test.
