David's gone on to compose music for various stage performances, both comedy and theatrical.

His first book, a comedy how-to guide on technology is called "Screw the Cable Company" and was published in 2016. He writes extensively about technology and cybersecurity for Medium and his short stories have appeared in magazines and websites around the world. For nearly twenty years, David has both directed and produced the critically acclaimed theater troupe "Fake Radio". The troupe specializes in re-creating radio scripts from the 1940s in front of a live audience.
