csv/txt to DB Import Export website

Very high skilled nodeJS developer needed. We want a website where user can import csv file of around 1million rows to DB. The import shouldnt take more than 5 minutes. So bid if u are confident enough for that. During the import, you need to check some conditions, and basing on that you have to again create some smaller csv files and at the same time add teh data to DB. There is one export function also to export DB info to CSV. Time and fee for this project is negotiable. But apart from that Import/Export module, other small things are really easy.
