GA4 Setup Verification for Shopify

I need an expert to verify our GA4 setup is correct. The focus areas include:

- Event Tracking
- Conversion Tracking
- User Demographics

We also need to ensure our Shopify funnels are accurately reflected in GA4, specifically:

- Product Page to Checkout
- Abandoned Cart
- Post-Purchase Upsell

I have noticed some incorrect data reporting that needs to be addressed.

Ideal skills and experience:
- Extensive experience with GA4 and Shopify
- Strong analytical skills for data verification
- Ability to troubleshoot and correct data reporting issues
