The Tizen App Challenge’s $4+ million is by far the big kahuna right now, but plenty of smaller prize opportunities are available to mobile developers. Designed to jumpstart the Tizen ecosystem, a number of hack-a-thons with jackpots are cropping up across the country. Dedicated Tizen developers Jakob Perry and Emilie Nouveau recently won a runner-up reward for their hybrid in-vehicle infotainment (IVI) app called Boomzbox. Jakob’s daytime hours are spent at Acquia as a senior software engineer, while Emilie works at MongoDB as a web developer.
