I have a master's degree in computer science and I'm working as a freelance consultant and software planning/implementation partner for SMEs in the Web area since 2006. My main area of expertise is CMS Systems (Joomla! and WordPress) as well as general PHP programming, MySQL, HTML5, JavaScript and CSS. I’ve developed numerous components, modules, plugins and templates during this time, for example helpdesk systems, payment systems (PayPal, Giropay, Paysafe, Micropayment) and publishing components (including social media publishing). Some of my software runs on platforms with 150,000 monthly active users.
