J. F. DIMARZIO began developing computer programs—specifically games—in 1984 as a wide-eyed, curious child of the Atari age. Starting on the TRS-80 Color Computer II, in BASIC, he wrote several small text-based games and simple inventory applications. After leaving the Music program at the University of Massachusetts, J. F. moved into professional computer development; working for the United States Department of Defense, Walt Disney Imagineering, TechData, and The Walt Disney Company. In 2008, he started developing apps on the newly introduced Android platform (then on version 0.8). He has had 14 books published to date, 7 of which are on Android and Android game development.
