    Technology Specialist

    United States - Last active: 12/15/2014 - Tests: 8 - Portfolio: 2

    Over the last decade or so, I have dedicated my life to the advancement of technology in all its forms. I have created numerous websites, databases, programs and specialize in audio/video integration and system design as well as room automation and signal processing. If I had to say I had any one real skill, it would have to be that I am profoundly good at building a better mousetrap. I must admit that there are times when I have difficulty creating things from scratch, but with a little inspiration I can take a project to a whole new level of design and implementation. I have experience in C/C++, MySQL, PHP, JavaScript, HTML/DHTML/XHTML and am moderately proficient with Lua, Ruby, Perl and VisualBasic, but not enough to brag about. I can interpret most programming languages easily enough.
