Experience
Edmonton ICU for Android and iOS
https://play.google.com/store/apps/details?id=com.edmontonezpfcc.EDM_ICU_MOBILERound Robin Form Service
The client oversaw facilitating communication to a small group of specialists but found that certain specialists were contacted disproportionately, causing an uneven distribution of work. This application was created to evenly distribute these work requests among the group of specialists fairly and anonymously. Administrators create and add a set of embedded forms into the application's database, each form linking to a specific recipient's inbox. When end-users log into the site, they automatically get a form based on previously accessed forms. This ensures a fair distribution of requests in the given group and removes any personal bias from the equation. The site was developed using Django.

Given their large facility, the client had issues with staff leaving and setting the alarm while others were still in the building. They wanted an app available on user devices and on mounted tablets by the entrances to allow users to sign in and out of the building and ensure that no one else was present.
I designed the iOS and Android app and the accompanying back end that handles the sign-in and sign-out. The back end was built using the Django REST framework.
