Apps like popl.co NFC

m looking for a freelancer to create a social media app similar to PoPL.co for IOS / ANDROID The app should be in sync with any NFC. So I’d like to make a social media app exact as POPL.co. I can take a new NFC chip, read the QR Code, takes me to the app to download. User registrations sign-in or Login, then 1 new user can input all of social media usernames accounts to sync as contacts. I would like the app to have control features on privacy. To allow which content to view which video/photos to view to others when sharing contacts. To also record ratings and views on each social media app.
