I was hired to build the 4SCENE app and take it from a 1.0 to 2.0. This app was deeply integrated with Facebook for authentication and friend finding.
The app was basically Snapchat meets location. You could upload pictures/Videos and it would be tagged with where you were currently located. User could search a map and find things happening near them, or in cities they would be visiting.
This was a fun project because it's what allowed me to learn Swift and release an application with it. Gone are the days of managing memory!
