Custom Development Project

I need someone with a high understanding and proficiency in PHP, CSS, MySQL, Bootstrap, JS to implement customizations on WordPress Generally, you have to add functionalities to my WordPress site.. pls look below My site offers customer to buy a pet tag with QR code, the QR code will be printed on the tag, and once scanned can reveal pet profile also send an email alert to the pet owner. From a user perspective 1. Customer purchase a tag from our website 2. They can log in into woo-commerce my account (dashboard) and select pet profile, they can have multiple pet profiles if they purchase multiple tags (order quantity more than 1). 3. They fill in pet details 4. If the pet gets lost, and someone scanned a QR code that redirects the user into opening the pet profile, the pet owner will receive an email alert 'tag has been scanned at (location of where the tag was scanned)' 5. If the pet owner opens the pet profile through URL or in preview mode, it will not trigger the email alert (only by scanning QR code will trigger an alert). 6. they can log in into woo-commerce my account dashboard anytime to edit their pet profile From an admin perspective 1. Upon receiving the order (customer checkout completed), admin can view the pet profile on woocommerce>my orders that are associated with individual order 2. A QR code will be generated related to the order, if someone scans the QR code, it will direct the to the pet profile 3. I will print the QR code to the tag and ship it to the customer 4. customer get the QR code and if they scan it, they able to see it and then get email alert Please suggest me how do you seek to resolve the following issues: 1 - QR code scan will trigger email alert about the location of where the tag was scanned, and the preview mode will not trigger an alert 2 - If a customer purchases more than 1 tag, can it be more than 1 pet profile? 3 - What technologies stack will be used to design frontend?
