As the multimediaguru within the Developer Services team she provides technicalconsultancy across all areas of Symbian OS, with special emphasison hardware. Adi was responsible for communicating Symbian'sroadmap to silicon and multimedia partners, and also led Symbian'scomponent validation program. Away from technical work Adi has beeninvolved in setting up the Symbian China partner-consultingorganization and is in much demand for her presentation skills,having given sessions at a wide range of partner and industryevents, including 3GSM World Congress.
Mark Wilcox has been playing with computers since his dadbought a ZX81 when he was four. He wrote his first multimediaapplication (a three room text adventure with sound effects!) on anAcorn Electron when he was seven. Mark has a Masters degree inMathematics, following this up with a research postgraduatein Cybernetic Intelligence. In 2001 he started developing softwarefor mobile phones and since then has been involved in handsetdevelopment projects for Ericsson, Fujitsu, Nokia, Panasonic andSamsung. During this time he's worked on everything from aGPRS stack, device drivers and a power management server tomessaging applications and the code that draws the soft keys. Itwas while working as a Software Architect for Nokia'sMultimedia business unit, developing their flagship Nseriesproducts, that Mark developed his interest in the multimediacapabilities of Symbian OS. Mark became an Accredited SymbianDeveloper and a Forum Nokia Champion in 2007.
