Wrote an iOS Battleship-style logic puzzle game for the iPhone®, fully capable of generating new puzzles with unique solutions and step-by-step hints. Developed Macintosh® applications to automate bulk photo resizing from collections of very large digital scans, to train and to exercise musical pitch and interval detection, and to organize digital movie collections. Created a video cropping and sizing calculator in Python/Tkinter and ported it to Objective-C for the iPad® and Java® for the Nexus 7™. Started designing a mobile app for tracking and rating specific product purchases, just prior to joining PlanGrid.

Designed and/or validated seven different microprocessors for Intel Corporation, across the Pentium® II, Itanium®, and Xeon® processor families. Specialized in the logic design of very large, last-level cache memories and their testability features. Modified existing cache line eviction and error correction schemes to support adjustable array size and latencies in a single device. Co-invented and developed a new banking and redundancy scheme for a last- level cache, saving several watts of power and winning a yearly corporate power reduction contest. Co-wrote conference papers detailing ideas for reduction of both active and leakage power in very large caches. Validated portions of several products both before and after initial hardware samples by designing software tools in Perl, Python, and C++; writing tests; analyzing test behavior; and inspecting logic code. Managed a small team responsible for debugging electrical and logical issues exposed by production test patterns.

Designed, maintained, and supported multimedia surveys, including one for the French utility company EDF measuring consumer acceptance of new billing methods. Created a Java®-based GUI framework for conducting online surveys and for guiding users through complicated purchase decisions, such as investigating, choosing, and purchasing a new vehicle. Assisted MBA researchers with focus group studies on building trust through agents and user interface elements.

Briefly developed a news feed viewer for young students as part of a research project. Ported to the Macintosh® and designed a GUI for an early version of the Salient Stills software application, which could process many frames of video and condense them to a single large still frame with very high pixel density or produce panoramas much like QuickTime® VR. Refined the application using CodeWarrior® C++ standard libraries for cleaner and smoother performance.
