Vancouver, Bc, Ca

- Wrote pipelining tools in Python and Shell that saves VFX artists an hour a day in content creation that would have been spent manually wrestling networking operations, data transfers, naming conventions, render farm tasks and render errors- From scratch, developed and continuously supported a Django (Python) backend, JS and Bootstrap (CSS) frontend web app for artists to locate, and stitch together video shots from a network of terabytes of assets- Automated the production and transferring of demo reels for the production team and artists in a few clicks instead of what would have been hours of emails, searching for relevant data, and managing approval status’ between supervisors

Vancouver, British Columbia, Ca

- Wrote essential gameplay features in C# and its associated unit tests that allowed up to hundreds of in-game units to be aware of mutual proximity and determine mutual visibility in 60fps gameplay.- Worked tightly with the design and campaign teams to design C# Unity tools and work flows that saved the campaign designers hours of work.- Maintained continuous integration of new builds using Jenkins, allowing the development team to catch bugs that would have otherwise been committed and speeding up debugging by at least an hour per dev per day.

Vancouver, Bc,, Ca

- Implemented Sensor Fusion (GPS/INS) algorithms in Native Android C++ to allow geo-positioning up to 100 times more accurate than raw GPS data, and enable continuous positioning even during short GPS outages.- Wrote Android applications in Java for HUDs that required timing accurate, multithreaded logging of processed sensor data at 1000 Hz to test the accuracy of sensor outputs to confirm algorithmic improvements of sensor fusion.

Olathe, Ks, Us

- Debugged firmware level issues in company products written in Embedded C.- Collaborated with teams working on commercial products to develop tools that aid in testing.- Wrote a C# application that establishes connections between ANT+ low powered wireless devices for easy data management. The application’s GUI design and automation saved the company half the time that would be spent if using an older version of the application.

Vancouver, British Columbia, Ca

- Effectively communicated user experience issues and programming bugs with specialized teams consisting of designers, project managers, and developers using ticketing systems such as Trac and Springloops.- Wrote Selenium scripts in Java to automate repetitive QA tasks that would otherwise take hours of daily manual labor.
