Shopify Store Enhancements and Customizations

I need a skilled developer to enhance my Shopify store with several features to improve user experience and engagement. Here’s a detailed list of the tasks:

1. Implement 'Get in Stock' alerts for sold-out items.
2. Create a 'Report Expired' button, similar to pzdeals.com.
3. Develop a custom app for sharing products on WhatsApp.
4. Integrate logos from Amazon and Walmart, where applicable.
5. Position 'Featured Products' either at the top or bottom of the site.
6. Place Google Ads between 4 products on the mobile version.
7. Resize Google Ads to be smaller on the desktop.
8. Position smaller Google Ads at the top of the site.
9. Implement a 'Copy Coupon Code' button, similar to pzdeals.com.
10. Modify link-sharing to include price and design, not just the image as seen on pzdeals.com.

The theme I’m using is 'Other' and I currently have a few apps installed. The most important feature I need right now is the placement of 'Featured Products'.

Ideal candidates for this project should:
- Have extensive experience with Shopify and its app ecosystem.
- Be proficient in custom app development.
- Understand eCommerce best practices.
- Have a keen eye for detail and design.
