I started doing the architecture and programming of J2ME applications for a very large mobile client in the US.

Another project concerned a performance analysis and re-factoring of a Content Delivery System for mobiles. This uses OTA, J2EE and WML technologies, as well as DRM. The platform was transferred from WebLogic 6.1 / JDK1.3 onto a JBoss 4.0 / JDK 1.5 platform with Hibernate and time-caches. Several operations in the database were significantly improved.

The final project here concerned a project management solution using GWT as the client front-end with Sharepoint integrations for a large client in Germany.

Dual purpose officer makes you navigation officer and engineer at the same time. The job involves switching from deck and bridge duties to engine room duties every couple of weeks. In short, all activities on a ship are to be executed by this type of officer. I sailed on the largest ships available, worldwide. The majority of trips I spent in Australia, Singapore and New Zealand with other trips going around both capes. I set foot in all continents.
