My experience mostly in business computing and information system area, using Spring MVC or JSF as web framework, and Spring Core or JBoss Seam as Integration framework, and Hibernate as favorite Java Persistence API (JPA) implementation.

During my work, I am using my Thinkpad T430s with Intel i7 processor, 16GB of RAM, 256 SSD and 23 inch external monitor that running latest stable version of Ubuntu Linux.
