One of my more recent mobile app projects, this app I worked on is a PhoneGap build built with Framework7 and Parse.com API. The parse javascript API is works with the Parse server which is a MEAN stack created by Parse.com a company now owned by Facebook. There is also a separate internal use backend web application I worked on as well. I added many features to the mobile app and backend including class level permissions to control which content users have access to, improvements to the administrator forms involving file uploads, Google directions with map in both mobile app and admin,  templates of the many pages as well as PDF creation templates.  Also I The app is not officially released yet but it will eventually be published on IOS, Android, and Windows which I setup and submitted the app for review and testing.
