Hi,
I have about 15 years of experience in java, JavaScript and associated frameworks . I have also extensively used Jasper reports in my previous assignments .
What I understand from your problem statement is that you are looking for building a web based (?) application wherein the user can select the columns he wants and generate reports in both csv and pdf off of these columns/selections.
Do you already have the list of columns,tables already defined where these lists would populate from ?
Please note that the bid amount and time is indicative and might change based on further clarifications.
Kindly consider my proposal.
Regards,
Rabiya
