Add some featues and changes into a working cloud (upload/download[dropbox like]) website

Hey, this is an project where I need some changes in my cloud website. So there are lots of changes, so there is enaugh work to do for this project, this project can be take maybe more than 3 months. So for me it is really important that the developer has read the description und which Skills are required: - You need to be a professional in cloud computing architekture - You need skills to develop encoding datas by upload/download (ssl / tls) - You need skills in creating features like in dropbox (versioning of datas etc.) SO please have a look on Dropbox, and have a feeling if you can do that too. - You need really skills in creating a good architekture for upload/download files. So please enter in the description cloudwebsite2015 that I can see that you read the product description really, if you dont write "cloudwebsite2015" in the description, I dont give the projekt to you! I will write you a message after that, with all the important information. I created a document, where all steps are documented. I hope I can find a group of developers or a developer which I can work in future. Greetings, Tolga
