    Navjot Sandhu

    Software Engineer with graphics specialization

    Canada - Last active: 4 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.

    Writer, Editor, Content Manager

    United States - Last active: 1 day ago - Tests: 6

    I excel in the creation of content. I'm available to write professional materials, such as manuals, notifications, and emails, in addition to creative work, like short stories, plays, and novels. 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. I know my way around WordPress; I can tweak your work for SEO; and I created and published an article every day for 19 weeks for Geek Smash, a geek news website, in addition to editing the articles of our entire writing team. In short, I'm your guy. When do we get started?
