I have had an awful experience with Kaushik. He is a liar and not a reliable developer!!! Terrible at communicating ! We divided the project into 2 phases. When he completed phase 1 (server setup+tests and verifications), he told me that everything was working, and I paid for phase 2. I could not test...
