    Senior Developer

    United States - Last active: 2 days ago - Tests: 1 - Portfolio: 1

    I have a degree in Computer Science and have been working as a contract web developer for quite a few years now. I've worked in many languages and technologies over those years and, given the proper frame of mind and incentive, I'm perfectly fine with learning something completely new to get a project done. Recently I've been moving into iPhone and Android Development but have also spent a lot of time working with PHP, MySQL + Postgresql, Laravel, Ajax (Json), JQuery, MCV + Activerecord patterns, MongoDB/Map-reduce, Facebook/Twitter/Google social APIs and Twillo SMS APIs. Real estate is almost a specialty of mine: Specifically data-mining (including scraping) real estate information and working with IDX and RETS property feeds. In the past I've also spent a lot of time working in ColdFusion and with C++ COM objects. Basically a jack-of-all-trades full-stack developer.

    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.
