Hi, Dear client, thanks for your job posting.
As a full-stack developer, I have rich experiences to create QR codes in PHP with APIs.
If you tell me how and where should I get the name of the shop, VAT number, etc, I can start right now.
I'm perfectly able to do this Job and I assure you that it will give you quality work in less than anticipating time.
I am waiting to chat to discuss more detail about this job.
I will do my best.
Best regards.
Vadym K.
