android & ios application

I already have 8 scenes in unity
-i need freelancer to create a home screen
-the home screen has a QR code reader
-when a specific QR code is scanned, switch to the corresponding scene (one of the 8 scenes)

i will share the unity project with the freelancer when we agree
freelancer to build android version and send it to me
freelancer to build and upload ios version to app store

i will provide all the ui assets
