Awesome developers ror developers needed to build a contest based website similar to talenthouse.com

Hello upworkers( Apply on if you can deliver a rapid prototype)\r\n\r\nI am using upwork to build a rapid prototype that is market ready. I am looking at a three week turn around time.\r\n\r\nNow coming to the website, I am looking at an application that helps brands to post contest/ campaigns and ask users to submit their work based on the creative brief.\r\n\r\nThe submissions could be video uploads/ image uploads/ gifs . Reference :[login to view URL]\r\n\r\nThe following are the tasks that I wish the developers to look at :\r\n1. User authentication using oauth 2\r\n2. Member profiles\r\n3. Login for brands to create campaigns and monitor the data\r\n4. Voting facility on each work submitted by the user...reference: [login to view URL]\r\n5. Social sharing buttons on submitted works ( refer the above link with social sharing buttons that reflect the name of the member)\r\n\r\nThe scope of work is only related to developers who are proficient in either ruby on rails or core php.\r\n\r\n
