Robert Zimmerman, who a lot of people just call ZIMM, is the single full-time employee of Bug Logic.
So, ZIMM is your project manager when you're working with Bug Logic.
When other back-end or front-end developers are needed they're brought into the job on the basis of their speciality. These folks are affectionately called the Bug Logic Brain Trust.
From the mid 1980's until the early 2000's ZIMM was primarily a commercial illustrator, working as a doodling gun-for-hire with such publications as The New York Times, Newsweek, Time Magazine, The Atlantic Monthly, US News a& World Report and dozens of others. A lot of heavy lifting was done for corporate clients as well, including Target, American Airlines, Hertz, McDonalds and AT&T to name-drop a few.
