Software development for the Maguro oHG.
Extension of the product NetDoc server. This product allows to document the local network structures and logged in computers based on Active Directory.
The extension was to extend the support for laptops: Every time a laptop starts up it creates a XML file via VBScript that contains the current state of the laptop like insalled software, bios-version, attached hardware, etc.
As soon as the laptop is connected to the local network it delivers the created XML files to a webservice that stores the data in a MS-SQL database.
The webservice was programmed in C# with Microsoft Visual Studio 2003 .Net used as IDE.

J2EE |
Serverside development of the MMORPG "Hellbreed" in Java using J2EE, Hibernate, Spring, JBOSS Seam, Apache Commons.
Responsible for conecption and programming of the game server and backend. Using the backend, the game designers could modify the values of the complex role playing rules for weapons, armors, spells, special abilities and loot. The modified values could be tested immediately in the game.
An item generator was used to calculate the properties of generated items on the fly. Depending on the value and calculatd properties a fitting name was generated using name fragments. The better the item was, the more parts had the generated name.
To make the replay of already discovered locations more interesting the monster values where increased or monsters where replaced by stronger variants of their kind, depending on the level and number of players in the area.

Development of webservices for ComBOTS AG using Java (J2EE).
One webservice was responsible for handling the installation and automatic update processes of their product called ComBOTS (client). The client consisted of multiple components that could be updated individually, when a new version of the component was released. On startup the client sent its version to the service and the service checked which files of the components where modified and need to be updated. This was implemented using version specific ZIP files that where dynamically created on demand and cached. So when a client connects with a version number and a corresponding ZIP file does not exist in the cache, it is automatically created, otherwise the cached one is being sent to the client.
Another webservice created personalized Installer.exe files.
The architecture of the webservices was designed so that modifications of configuration parameters were taken into account immediately without a restart of the service. The params could be modified using JMX or by editing the config files.
Used technologies:
Eclipse, Maven 1, Maven 2, Jakarta Commons, JAXB, JMX, Oracle, Servlets, Spring, Subversion, Tomcat, XML, Windows and Suse Linux Enterprise.
