I've managed to eke out a living writing code for Java based web applications since 2002. Started with all Servlets, advanced to JSP and Struts, followed by Spring MVC and RESTful web services serving a BackboneJS UI.

I write SQL queries/functions/procedures/packages for primarily Oracle databases, with some experience with IBM DB2 and MySQL. I'm fairly experienced with Hibernate specifically, and JPA more generally/abstractly.
