Since January 2002 (full-time since September 2002) I've been working with Java. Almost all the time I've been developing Java EE (J2EE) applications, ie. I had a running Weblogic or JBoss instance on my box where I did all of testing and debugging.

Below is a a brief list of major projets I've participated. Before reading it you may consider having a look at a list of programming books I think are worth reading, a list of my Java EE links, a my technical blog.
