    Graphic / Web Designer

    United States - Last active: 5 days ago - Portfolio: 1

    For 15 years, I have worked as a Graphics and Web Designer. I've done extensive work designing everything from CD jackets, poster boards, to magazine and book covers. For five of those years, I worked in my hometown of Tokyo Japan, under Tztom TODA design firm. I was also heavily involved in the design of www.rakuten.co.jp, the number one Internet eCommerce portal in Japan. My desire to experience and learn as much as I can lead me to America where I started designing websites. The San francisco Bay Area has been my home for the past 10 years and have enjoyed every moment of it. Most recently I've had the opportunity to design print materials for some of the fastest growing companies in the Bay Area. These print materials include folders, catalog sheets, business cards and even logos.

    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.
