David Gelphman is a senior software engineer on Apple's Graphics and Imaging team. He has over 20 years of experience working with the PostScript and PDF imaging model that is at the heart of Quartz graphics. His computer career began with scientific computing while he was earning his PhD in experimental particle physics at Stanford. Apple's introduction of the Macintosh in 1984 caused him to make a sharp turn into the world of user-friendly computing and he hasn't looked back.While working at Adobe Systems, David co-designed Apple's LaserWriter 8 printer driver and was team lead of the development project. At Adobe he also worked closely with third party developers, taught PostScript programming, wrote a number of technical notes, and contributed to the evolution of the PostScript language. After leaving Adobe he continued to combine software engineering work with documentation for software developers, authoring an article for Apple's develop technical journal in addition to a number of Apple technical notes. Today David writes system software for Mac OS X but continues to be involved with third party documentation and enjoys writing sample code for developers outside of Apple.
