Since 2003 I was studying information technology at Faculty of Electronics and Information Technology, Warsaw University of Technology. In 2006 I did one year break joining CERN as a technical student in IT-PSS group. During my stay I developed Streams Monitor tool which provided dashboard for all experiments to the distributed database environment. In February 2008 I obtained bachelor degree of software engineering. I have designed system of load-balancing cluster with web interface. In June 2009 I defended my master thesis concerning formal verification of concurrent systems. Afterwards I came back to CERN to the same group as an openlab fellow sponsored by Oracle. Now I am starting to work on Oracle 11g testing concerning streams replication.
