GigaOM’s Top 15 Mobile Influencers

Joe Hewitt, Programmer, Facebook

me Influence: In the world of software, there are few who qualify for rock star status. But Joe Hewitt, a New Jersey-born programmer, is one of them. He started out at Netscape in 2000, working on the browser’s user interface, after which he went on to help longtime cohort Blake Ross reinvent the Netscape browser as Mozilla’s Firefox. In 2006 he left Mozilla to work with Ross on a new startup, Parakey, that in turn was acquired by Facebook in 2007. Then when Apple launched the iPhone, Hewitt released iUI, a user interface library that consisted of a combination of javascript and CSS and allowed for the easy development of web applications that matched the device’s native visual elements. Later he wrote an iPhone-specific version of Facebook, which has helped to both take the social network to the top of the mobile heap and jumpstarted the adoption of social networking services on all major mobile phone platforms. What’s even more surprising: Hewitt is the one-man programming machine behind Facebook for the iPhone.
