Super Secret ???
This project is currently under wraps and is only available as a private beta, so we can't say very much.
However, what we can say it is a social network platform that relies heavily on video.
We've built the whole end to end system from the ground up and pending funding will be working closely with the founder to bring the product to market.
The screenshots should speak volumes.
The Techie Bit:
Currently iOS only (it will eventually support Android), built using Swift 3.
Lots of custom UI code including things like custom CollectionView layouts, some AVFoundation and background services.
Server side we use Firebase, Amazon S3 and some micro services written in AWS Lambda.
