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

    Germany - Last active: 20 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.

    Javascript/Node.js/ASP.net Web Developer

    United States - Last active: 10 days ago - Tests: 2

    Since 2000, I've been creating web content using a variety of languages and platforms. Regardless of the languages I've used, the most important one is the language we use to communicate your vision, requirements, and acceptance tests. Indeed, the keys to mutual success are kept by good communication. It is with this mantra that I worked as a contractor at RF Microdevices, Wells Fargo, and Dorsett Technologies. In working for these companies, I accomplished the following: used end-to-end Javascript solutions to create line-of-business applications; federated Javascript in a large, legacy ASP.net Webforms application; used jQuery, jQuery UI, underscore, Backbone, Knockout, KnockBack regularly; I created truly RESTful handlers in legacy ASP.net Webforms applications; authored custom user-experiences and javascript plug-ins, used MongoDB and SQL as datastores, wrote server code in C# classic, C# Lambda, Javascript, and CoffeeScript.
