    Software Engineer with graphics specialization

    Canada - Last active: 5 days ago

    I'm currently completing my second Masters, a Master of Computer Science in Human Computer Interaction in which my thesis is on 3D user interface design and methods, essentially creating a new system from scratch. I can work with the desktop and mobile devices, using WebGL, OpenGL ES, DirectX11 and OpenGL 4 specification. I know how to create all types of shaders in glsl and hlsl, and work with immediate mode and the new pipeline very well. I also have learned how to take pseudo code from research and books and implement them as well in shaders. I can apply engineering principles for optimization for rendering engines, and do client/server work as well in c/c++, java, and objective-c, as well as work with computer science algorithms for creating specialized effects and utility functions. I can also program for mobile devices, primarily in iPhone and Windows phone, though I am able to work with Android also.

The same holds true for my editing expertise--I've worked as a content manager and edited technical manuals, contracts, and the like, but I've also received a master's degree in creative writing, so fiction is a major facet of my life. Finally, I'm tech-savvy and web-smart.
