Hi, I'm Rob!

Hardware hacker by day, design deliriant by night; I’m an electrical engineer with a passion for human-computer interaction, music, and rapid prototyping. I use my powers to build functional models of wild ideas for both myself and clients using hardware and software.

I hold a BEE in electrical engineering and a MS in computer engineering from University of Delaware, as well as a MS in Music Engineering Technology from University of Miami (Florida). I’m an avid runner, and my bicycle is my main mode of transportation year-round. In my spare time, I also enjoy creating rotoscopes and illustrations, reverse engineering electronic toys, and taking a break from screens by camping and hiking in the great outdoors.
