    Senior Developer

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

    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.
