hi.. i went through your proposal and sounds very interesting to me.. For your information, i have more than 2 years of experience working with spring and hibernate. Designed UML and sequence diagram using eclipse plugin(amaterasuml), rad and visio. Further, to be honest, i have never worked with zk but have worked with various frmaeworks like vaadin, kendoui etc, which, after going through zk's site seem to be similar. I would be apt for this job, for any clarification, you can PM me..
