Employment
Experience
- MSH (Development)https://itunes.apple.com/us/app/msh-labs/id1135125551?mt=8
The team wanted to build a highly interactive and fluid interface—heavily leveraging iOS animation capabilities and real-time server communication.
I joined the project during the ideation phase and brought the product from a set of mockups to a production-level application available in the App Store. I built the majority of the iOS application as well—deciding on the architectural patterns used along the way to support a robust, lively application. In addition to the iOS application, I built a Phoenix web application running on Heroku which leverages WebSockets to support the real-time nature of the application. - Looney Tunes Dash! (Development)
Zynga's cross-platform 3D game exploring the Looney Tunes' universe.
I led the Android development for the project—building a cross-platform architecture utilizing C++ to run on both iOS and Android. I also regularly assisted in building the iOS front-end in addition to leading the Android development.
Looney Tunes Dash! received an Editor's Choice from the iOS App Store after the release and reached an audience of over 100 million players - Meditrain (Development)https://neuroscape.ucsf.edu/technology/#meditrain
Dr. Gazzaley of UCSF's Neuroscape lab wanted to build an immersive, adaptive meditation app for use in clinical trials measuring the effects of meditation.
I was responsible for both architecting and building the iOS application which supported engagement features like a calendar and progress-tracking as well as the core meditation experience with an adaptive loop.
UCSF's lab was extremely pleased with Meditrain and there is a patent filed and pending. - ACE (Development)https://neuroscape.ucsf.edu/technology/#ace
Dr. Gazzaley of UCSF's Neuroscape lab wanted to build an engaging, interactive mobile cognitive assessment tool that evaluates multiple dimensions of cognitive control quickly and without ceiling or floor effects.
I was responsible for the architecture and implementation of the iOS application, including 11 cognitive tasks and their adaptive algorithms.
UCSF was satisfied with our work on ACE and intend on making it freely available to the public worldwide. - Farmville (Development)https://apps.facebook.com/onthefarm/
While working at Zynga, I spent time building growth features for the famous web game Farmville. I worked in PHP writing both the front-end and back-end code to implement features designed to bring in and retain users.
