Work Experience

Google Inc.

Software Engineer (November 2012 - January 2020)

  • Tech lead for Cobalt, YouTube's application-container platform for living room devices.
  • Collaborated with TV device partners to promote adoption of Cobalt across the industry.
  • Designed the Cobalt graphics rendering stack, enabling improved framerate versus Chrome on embedded devices.
  • Implemented OpenGL for platforms like the PS3, PS4 and WiiU which don't provide it out of the box.

Next Level Games (NLG)

Programmer (January 2005 - April 2005), (September 2005 - December 2005), (May 2007 - 2009)

  • Dramatically improved the framerate in Punch-Out!! by utilizing the Wii's locked cache resources.
  • Augmented silhouette algorithm to greatly improve appearance of cartoon character rendering in Punch-Out!!.
  • Designed and implemented a networking library on top of the Wii's networking API in order to provide truly non-blocking asynchronous calls.
  • Architected the gameplay structures and networking system in the Xbox Live Arcade game, Ticket to Ride. The game's networking model was client-server based, with support for server migration if the host drops.
  • Interviewed many potential future co-op students to fill the role of software developer.


Software Engineer (May 2006 – August 2006)

  • Developed driver code for NVIDIA's GoForce products.
  • Implemented power-saving functionality to disable chip features while they are not being used.
  • Implemented system to record low-level communication the driver makes with hardware. The startup process was recorded and its playback enabled quick display of a splash screen on device bootup.

Sun Microsystems Inc.

Software Developer (September 2003 - December 2003) (May 2004 - August 2004)

  • Developed functionality for Sun's Enterprise Learning Platform web application under Enterprise JavaBeans.
  • Developed tools in Perl to automatically generate graphs and reports based on data queried from Sun's bug database.  These enabled managers to make better decisions regarding bugs.

  • Awards
  • Won the Western Association of Graduate Schools (WAGS) 2013 Innovation in Technology award for my thesis.

  • TurtleSeg
  • I developed an interactive 3D image segmentation tool called TurtleSeg ( Since going public in February 2011, it has been downloaded all around the world by research institutions, hospitals and businesses. TurtleSeg is a proprietary software owned by Oxipita Inc.

  • GPA: 4.33 / 4.33

BMath in Computer Science from the University of Waterloo (2002 - 2007)

  • Average grade among CS/Math courses: 88%

Personal Projects

  • (2008) Dynamic 3D Scene Graphs Created a proof of concept implementation of an dynamic 3D scene graph system. It allows for 3D scene graphs composed of objects of vastly different scales, and loops are allowed (i.e. a node of the scene graph may feature itself as a child). Implementation includes a creation tool and viewer tool. I wrote an article about this work that was published on (Link).
  • (2006) [School Project] Real-time operating system + Train Controlling Application Created an x86 real-time operating system. On top of the OS, I successfully created a train controlling application which managed multiple trains navigating around a real-life model train track, while avoiding collisions.
  • (2006) [School Project] Virtual Foosball Created a 3d video game of foosball, called Virtual Foosball. Game features include ball physics, networked multiplayer games and instant replays. (Link).
  • (2005) Marching Tetrahedrons Demo Created a screensaver which implements the Marching Tetrahedrons algorithm with post-processing involving mesh simplification and mesh subdivision (Link).
