    Software-Developer (PHP, MySQL, Javascript, AJAX, Symfony, jQuery)

    Germany - Last active: 19 days ago - Tests: 4

    Since 2006 I implement PHP/MySQL Database Applications - starting with the simple CMS-Website over Online Shops with backend interface to existing software, ending with high-demanding customized business applications - with established languages and techniques like XML, HTML, CSS, AJAX and Javascript and several CMS- and E-Commerce systems as well as Frameworks. In the last years Pimcore, AngularJS, Symfony2 and Knockout were my regular tools of occupation, but I'm able to quickly read myself into other systems. Also I was able to extend my knowledge about Mobile Development with Objective-C for iPhone/iPad/iPod-Apps, as well as Java for Android. In addition to that I realized several Database Publishing projects – automatized catalog production - with direct, standardized PDF- Creation or with Indesign-Plugins e.g. Werk II's priint:comet oder DATAFORM.

    Senior Developer

    United States - Last active: 17 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.
