Shopify + Meta Pixel Audit & Dynamic Retargeting Setup (Fix Existing Tracking Issues)

I'm looking for an experienced Meta Ads technical specialist to troubleshoot my existing Shopify/Meta setup and build a working dynamic retargeting campaign. This is not a general Facebook ads management job. My primary goal is to fix my tracking and ensure dynamic retargeting is working correctly. Current Issues My Meta Pixel appears to be attributing purchases to the wrong products. Previous retargeting campaigns have spent $0 despite my store receiving significant website traffic. I want to verify that my Shopify integration, Meta Pixel, Conversion API (if applicable), catalog, and events are all configured correctly. Scope of Work Audit my Shopify + Meta integration. Troubleshoot and fix any Meta Pixel issues. Verify product attribution is working correctly. Verify the Shopify product catalog is synced properly. Confirm ViewContent, AddToCart, InitiateCheckout, and Purchase events are firing correctly. Fix any event mapping, product ID, or catalog issues. Set up a dynamic retargeting campaign that shows visitors the exact products they viewed. Verify the campaign is eligible to deliver and explain why previous campaigns may not have spent. Walk me through what was fixed so I understand the setup going forward. Requirements Extensive experience with Shopify stores. Strong understanding of Meta Pixel, Events Manager, Conversion API, Dynamic Product Ads, and Shopify catalogs. Experience troubleshooting existing tracking issues (not just installing a new pixel). Able to diagnose why campaigns are not spending. When you apply, please include: A brief explanation of similar Shopify/Meta tracking issues you've fixed. Whether you've set up dynamic product retargeting campaigns before. Your proposed approach to diagnosing this type of issue. I'm looking for someone who can own this project from troubleshooting through a fully functioning retargeting setup.
