Looking to build simple "Customer information" contact list for Mac OS - Must have AWS experience

Hello all, Please make sure you read everything before you apply or message me as I will not be explaining what I need as everything will be in this ad. I'm looking for an independent developer to make a simple small application for me. The following is the requirements. 1. You must be able to develop for Mac OS Ojbective-C or Swift. 2. Must be proficient with AWS ( Amazon Web Services). 3. Must work on it have it full time till done. Since we have the formalities out of the way, here's what the project needs to do. I do not need it to look good or be deployment ready, I just want bare bone shell. Nothing extra. Main requirements 1. Application should have the following a. Two fields to be filled by user – First Name, Last name b. Save button – Application should cross reference the First Name and Last Name and indicate if that contact already exists in the list or not. c. Contact information should be viewable as table where users could edit/delete. d. Application should have SEARCH function for contacts in list. 2. Here’s the most important part a. Application should save everything as a CSV file on the AWE server (I have the server will give developer access when ready) b. Nothing should be saved on device, everything should be on server and viewable from multiple computers and users should be able to Add/Edit/Delete information which should be updated live on all applications from multiple computers. (Very similar to Google Docs) Please see screenshots provided.. PLEASE MAKE SURE YOU ARE 100% CERTAIN YOU CAN DO THIS APPLICATION BEFORE APPLYING AS THIS IS THE 5TH TIME I'M POSTING THIS.
