I'm working as freelancer with Java since JDK 1.0, with Servlets/EJB since 1.0 and before the advent of J2EE in several large-scale applications. I am an architect and developer (with usually 20/80 distribution) in Java (SE / EE / FX) projects.
I had edited several books about JavaFX, J2EE, and Java EE, and I'm the author of Real World Java EE Patterns—Rethinking Best Practices and Real World Java EE Night Hacks—Dissecting the Business Tier. I'm writing books and articles during my travels and sometimes even unproductive meetings.
In my leisure I participate in the JCP as an Expert Group member for the Java EE 6 and 7, EJB 3.X, JAX-RS, CDI, and JPA 2.X JSRs.
I am is also a Java Champion, NetBeans Dream Team Founding Member, Oracle ACE Director, Java Developer of the Year 2010 and I was chosen by attendees of my sessions as JavaOne 2009 and double 2011, 2012 and tripple 2013 Rock Star.
I'm speaking regularly on conferences, but I'm neither a professional speaker nor writer. I'm just really enjoying to write code and kill the bloat. ...and Java is perfect for that.
I'm organizing three times a year Java related workshops at Munich's Airport: http://airhacks.com.
