HI,
I see you wrote, your project is basic rest crud operations so i am guessing you need to expose new tables as a rest repository. If it is true that would be great job for spring data rest.
I am java developer using java 8, spring framework (data jpa, data rest, batch, session, mvc).
I have experience making 3 tier architecture, using hibernate, annotation based
configuration, RESTful services, mock objects, jQuery, js, ajax, marshalling objects.
Experience working on MySQL i postgres databases.
Depending on these 3 tables, I will expand persistence layer and add service layer for crud operations.
If you have any questions, please contact me.
