E-Commerce App Development, with AI for IOS and Andriod C++ Java

I'm on the lookout for an experienced developer skilled in C++ to help develop an e-commerce app for my Shopify store. The desired app should be designed with top-tier functionality inclusive of stellar features such as:

- User registration and profile management: This should include a secure system for users to register and manage their individual profiles.
- Comprehensive product catalog and search: I need an extensive product catalog with a user-friendly search feature that would allow users to easily find and compare products.
- Shopping cart and checkout system: Should have a seamless, bug-free checkout process supporting several payment methods to ensure a pleasant user experience.

Ideal candidates should have substantial experience in C++ programming and previous work on Shopify platforms. A strong background in e-commerce app development and a good understanding of user-centered design will be advantageous.
