    I am a Java Developer, working as freelance Java Developer, mainly in Upwork. I am very passionate in Java and java-related technology. My experience mostly in business computing and information system area, using JSF or Spring MVC as web framework, JBoss Seam or Spring as Integration framework and Hibernate as favorite Java Persistence API (JPA) implementation. Mostly using JUnit for testing framework, except for JBoss Seam, I am using Test NG which is bundled together with JBoss Seam distribution. I am also very interested in database design and software design. If my clients require software methodology to documenting my design, my favorite software methodology is Iconix Process. Iconix Process is simplified version of RUP, make The Iconix Process one of reasonable UML Based methodology to adopt.
