Authentication of IOT device via Scanner using P2P

I am in need of a freelancer to help authenticate an IOT device - a Smart Camera - using a QR Code. We will be using Wi-Fi Direct for the P2P technology. The freelancer should have experience with programming authentication to ensure the security of the device. We are also looking for someone that is knowledgeable in working with a QR Code to complete this project. If you have the necessary skills, I would love to discuss the project further with you!
