Being part of the backend team I am responsible for making the gameserver high performance. By regular profilings I'm up to find bottlenecks and working with the game developers to solve them. In addition to this incrementally optimizing the GC to meet our requirements of a mixture of consistent (not highest) throughput and GC cycles. At last I'd build the internal async framework to handle requests and queue the preserialized results in a native buffers to be picked up by Long-Polling.

The internally used offer calculation and booking system was completely rewritten from scretch and business and technical requirements were defined in coorperation with the operating departments. In a team of more than 20 people I was working (with 4 other peoples) on the deep internals of the offering process and calculation of best price offers. In a the clusterized environment we implemented a fully distributed, highly fast process for these kinds of calculations.

Building an online solution for recruitings and recruiting tests I was responsible for implementing additional test features and customer wishes to the recruiting test solution. The solutions were implemented as fully rich client HTML applications using ExtJS and JQuery. The backend stack included working with Spring and Tomcat as well as the database backend and Apache Torque as the ORM layer. On the recruiting solution there was a Apache Karaf stack with static files provided by an Apache webserver.
