For this project I worked out along with the founder an MVP version of his product idea.
Together refined on the product usability according to the potential customers needs he had in mind.
I worked on the UI/UIX in Photoshop back in 2013, generated the mockups for the main feature and proceed with the implementation of the first version of the app using Objective-C on Xcode.
Built the backend as well on Ruby on Rails which was required for communicating the user responses to the questions that could be configured in the app through a Plist file.
