+## The Work at IXOS SOFTWARE AG
+
+I started to work at <b>IXOS SOFTWARE AG</b> as an intern during my studies and worked on different projects.
+
+- Jetform integration into IXOS ARCHIVE on an R/3 environment
+
+- Mobile internet computing test for IXOS Mobile/3
+
+- IXtrain sysadmin while studying
+
+- Digital timestamp client/server application in Java
+
+- Porting the Perl/CGI version of the IXOS Jukeman website to ASP/SQL on the IIS
+
+After I stopped my studies, I started to work at IXOS SOFTWARE AG as a <b>Web Engineer</b>. My job was to build up a logical environment for all scripts and to enable <b>persons with no HTML experience to publish content on the www.ixos.com webpage</b>. This was done for press releases, event database, and later for job offers. I also integrated the index server search engine on the webpage, including PDF indexing.
