Module: ionic 2 + yii2 as api - picture/video gallery with upload - amazon s3 aware

General information for the business: Techonology
Kind of development: New program from scratch
Num. of modules: 1
Description of every module: Build a ionic-2 app/module for frontend and php7-yii2 framework for backend (as api endpoints) to upload personal pictures and video clips on a private cloud space and watch them individually or as slideshows, in a standard/full screen mode.
Description of requirements/functionality: The multimedia content module should provide:
* Storing files in amazon cloud
* Authorisation to the content using user accounts, allowing group access to content [users are groups aware and access to files are granted based on group membership]
* Grouping files in folders, at upload time
* Quota restrictions (per file and per account)
* File type restrictions (jpeg, jpg, png, avi, mp4)
* Move feature available (from one folder to another in the same account)
* Delete content (no recycle bin available)
* Slideshow presentation of the files
* Embedded movie player for uploaded video files
* Settings persistence (quota restrictions, …)
The authentication should be mocked up, as this app is a module of a bigger app.
