I designed and developed an internal data mining service based on Java and PostgreSQL as primary storage for a significant amount of data. A key data mining task was the automatic analysis of large-scale data and taking appropriate decisions based on a user in-game behavior. In addition a special web interface, based on SpringMVC, Hibernate and JSP/JSTL) was created for an additional human support where moderator could browse users' behaviors in a convenient way and perform supplemental… Show more I designed and developed an internal data mining service based on Java and PostgreSQL as primary storage for a significant amount of data.

In addition a special web interface, based on SpringMVC, Hibernate and JSP/JSTL) was created for an additional human support where moderator could browse users' behaviors in a convenient way and perform supplemental actions.Developed an internal REST API service based on SpringMVC to improve the integration between end-user services.Integrated code for users' behavior analysis into the concurrent environment of existed backend game service that had been written in Java. That integration didn't cause any speed degradation or bad affections on the user experience. Suggested a few improvements in the backend game service to decrease thread contention. Performed some measurements that helped to eliminate memory leaks. Show less
