I am a full time Java and database developer. Query and code for results caching is what I do. I would need access to the code and data, I don't mind how that is done.

Hello Yello, My name is Robert Sopinec and I'm a software developer in Ohio, US. I'm originally from Slovakia however 4 years ago I've relocated to the US. I've been working with DBs, Java and various frameworks for 8 years. It looks like a simple issue to me, so let me know if you want me to help you with it. You would have to tell me more about the project obviously. Have a great day. Thanks, Robert Sopinec
