Ruby on Rails, Firebase, AWS Backend needs update for current iOS App

Looking for medium level Backend Mobile App Development specialist.

- Ruby on Rails

- Firebase

- AWS

- Swift



I have an app in the AppStore currently that needs to a couple features to be tweaked: i.e. a modernized UI including Apple Pay and updated location services. Our backend needs to be adjusted to handle the new updates working with our front end developer.



I have a couple small tasks that require experience with Google Firebase connecting to AWS and iOS app. Mandatory specialty is knowing Ruby on Rails.
