About me

I am a self-employed web developer and security consultant since 2007 and based in Switzerland. I have built multiple websites, web applications and Joomla extensions for clients from Austria, Germany, the Netherlands and Switzerland in the last years. Since March 2014 I also run a backup service for websites. My provided services are site building, extension development and security consultation.

I have studied Computer Science with focus on IT security at the University of Applied Sciences in Bern (Switzerland). Before I went to Bern, I studied Computer Science at the Saxion University of Applied Sciences in Enschede (Netherlands).

During my studies I gained, inter alia, experience in object-oriented programming with Java, computer networks, web technologies, system software, device drivers, cryptography, network security and system security. In my self-employed work I have gained knowledge of PHP, MySQL, HTML, CSS and web related security topics.
