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

    Germany - Last active: 25 days ago - Tests: 4 - Portfolio: 18

    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.

    PHP,HTML,CSS,Java,JavaScript,Perl, Web Developer, MySQL, Linux: 10+yrs

    United States - Last active: 1 day ago - Tests: 6

    I have over 14 years of experience building, fixing and maintaining web applications and their back-ends (large and small). Web programming is my bread and butter- HTML/CSS and whatever drives it on a LAMP or LAMJ stack (PHP, Java/JSP, JavaScript, Perl, etc.). Plus I can administer the technology needed behind the scenes for database setup (MySQL and postgreSQL), maintenance, cron jobs, and systems administration (RedHat/Fedora/Centos or other Linux, etc.) Whether you have just a quick need for someone who knows their stuff, or a larger or ongoing project that might require recurring tasks, I'm here to help. I'm not a Jack of ALL trades, but I also am pretty savvy when it comes to website UI design, SEO and internet marketing, including email and social media.
