Experience

My consulting experience covers business analysis, advanced UI development, unit testing, and legacy development. Other projects include embedded and mobile software, line-of-business apps for the desktop, and music software.


Hardware test app

Java / Android SDK / Sockets

Developed test app for patient intake device used in many hospitals and clinics. App verifies hardware for manufacture and repair team; interactive tests check display, touchscreen, speakers, status LEDs, Camera, WiFi, USB, and Ethernet port, while automated 'burn-in' mode tests WiFi and USB functionality under sustained load. App forwards results to central test server for storage and review.


Geometry library

C# / Analytic geometry / Machine learning / Unit testing

Developed geometry library used to plan directional drilling projects. Designed and implemented several new geometry techniques that improve drilling outcomes. Also designed and implemented genetic algorithm that fixes user designs or creates new designs from scratch. Added hundreds of unit tests covering many thousands of test cases. Wrote extensive documentation for client developers.


Custom 'console' control

C# / Windows Forms / Multithreading

Developed complex Windows Forms control that embeds console-style output in any form. Control offers fast display updates with thread-safe write functions, and numerous formatting, scrolling, and wrapping options. Display buffer can be saved to or restored from file, and mouse-selected content can be pasted to RTF, HTML, or plain text. Finished control is used to develop specialized test apps.
