Google Maps for iPhone

Jeff built many of the core user interface components for Google's first native version of Google Maps for iOS. These core components were designed from the start to be modular and, after the resoundingly successful launch in December, Jeff focused on sharing these components with the rest of Google's iOS offerings.

June 2012 - April 2013

Notable work includes building a custom UINavigationController-like controller for presenting all of the views and transitions seen in the app, experimenting with the user experience for the sliding footer component and corresponding paging mechanism, and using Nimbus features to drastically reduce code complexity in the app.

Much time was spent in a conference room with the design team and Jeff's sound system backpack as they polished the app before launch.

Nimbus

The iOS framework that grows only as fast as its documentation.

Nimbus was initially created as a replacement for the Three20 open source framework but has since grown into its own as a fully-modular open source framework. It is because of this modular design that Nimbus has been integrated into so many projects and now drives critical components for well over one hundred million application installs.

Facebook for iPad

Jeff worked on the first version of the Facebook iPad app as a universal app that shared the existing iPhone app's code base. Jeff built one of the first implementations of the now standard "drawer" interface and ported this to the Facebook iPhone app.
