Microsoft PowerPoint add-in to store, update, delete and import slides over an REST API

I need a user interface for a Microsoft PowerPoint add-in where slide can be pushed to a database behind an REST API. The slide needs to be visualized this add-in, where they can be imported into the current presentation. The first task is to create user interface for this tool using. For the first prototype of this tool we would like get a user interface programmed. The data storage of the first prototype can be done in the memory or on the local file system. The stored Slides id needs to store as a TAG of the slide. The code needs to be provided for further development of the software. A follow-up project is possible. I would like to have the first prototype in two weeks. Milestone will be planned together. Below the link for reference what I am looking for. [login to view URL]
