Requires SQL Database Programmer (Very Big Data)

I need a SQL database application developer for profiling financial customers. It is a simple application. But the programmer must be Very understand about the search database method with very large data (TB of data). Usually works with Linux operating system. Can integrate SQL files into a complete application. Usually process data base in large quantities (import/export). Responsive web based application. Willing to make a Non-Disclosure Agreement (NDA). All source code is included in the cooperation contract. There are features of data management functions, including the new data import feature because the data will always evolve. Preference will be given to those who already have experience in making special applications based on SQL databases, not just web developers with little SQL data. Because the speed of search data is very important. Please attach a portfolio, sample applications that have been made and name your offers. Less offer is better. Thank you.
