I have a rails application built that uses the carrierwave gem to upload audio files locally when in development and to S3 when in production. I simply just need some one to develop a drag and drop multiple file upload that works with carrier wave. Each file must be its own instance, and not have a bunch of files in one array. A progress bar of each file upload is also a must, as well as the option to set each file name while being uploaded. I have a private repo on BitBucket with the source code that I will share to the person hired.
