Mindstrong's main iOS product is a data collection platform embedded into a keyboard extension. While working there, developed that keyboard's autocorrect accuracy to rival that of Apple's keyboard. In order to do so, performed deep research into academic papers, and performed additional deep research (via decompilation and assorted hacks) into Apple's implementation.To improve patient adherence, decreased the keyboard's startup time by a factor of 10 through dylib hacks and optimizations.Implemented many of the things that move an app from a proof of concept to a real product: CI, code linting, analytics, login flows, kill switch, HIPAA adherence, push notifications, localization, and so on.And finally, architected and build a new app, Care, intended for care providers.

Took part in in-depth research to identify Eventbrite's ideal user and her needs. Worked as the only developer on a small team building prototypes to test hypotheses about how best to serve those needs. Based on these answers, built a modern, production-ready app, Rally, and released it to the world to continue to develop our product ideas. Used that codebase as the foundation for the brand new, currently shipping iteration of Eventbrite's consumer app.

As contractors, Spaceman Labs built several award-winning apps. As a self-funded startup, we built Repartee, a mobile event-planning app. We launched it onstage at the Launch festival, live in front of thousands.

Did pioneering performance-oriented graphics work to achieve noteworthy visual effects within the constraints of first-generation iPhone hardware.Created most of the charts in Roambi, including highly interactive charts in the Catalist and Trend views.Implemented the Cardex view, both the iPhone and significantly different iPad versions–see the patent applications "Displaying Multi-Dimensional Data Using a Rotatable Object" and "User Interface for Data Comparison", below.Implemented the Squares view; designed the animated interactions. Said interactions were featured in Apple's video introducing the iPad Mini.

Presented "2D Graphics & Animation for iPhone and Mac" at WWDC 2008.Worked on iPhone demo apps such as Touch FX and Touch Fighter (demoed at the iPhone SDK introduction event), and City of Sound.Wrote Core Animation demo apps such as CovertFlow and CATV–the former being the most frequently referenced sample code for Cover Flow-like interfaces.DRI for OS X's event system.Re-worked window shadow implementation. See the patent "Methods and Apparatuses to Arbitrarily Transform Windows", below.Implemented fast, shader-based blur in the window server.Worked closely with Human Interface group on new features, Cocoa group on adoption and coordination.

Maintained code and added new features to both internal and external applications, such as Quartz Debug and Pixie. Created an automated web-based build and performance testing system in which three other groups at Apple expressed an interest for their own use. Created sample code to introduce developers to new Core Graphics API. Read the entire PDF specification.

Created a usable, powerful performance logging framework to run on the set-top box for use by multiple groups at TiVo.
