Shopify Meta Pixel Expert Needed to Fix Purchase Event Duplication & Missing Event Values

I am looking for an experienced Shopify, Meta Pixel, and Conversions API specialist to audit and fix tracking issues on my Shopify store.
Current Issues
Issue 1: Purchase Event Duplication
In Meta Events Manager, Purchase events are not being tracked correctly.
Current behavior:
Browser Purchase Events: 2
Server Purchase Events: 1
Need to identify and remove duplicate browser-side Purchase events and ensure proper event deduplication between Meta Pixel and Conversions API.
Issue 2: Missing Value Parameter in AddToCart Events
Meta Diagnostics reports:
AddToCart Event
"Value Field is Missing"
Approximately 35% of events affected
Need to ensure all AddToCart events send:
value
currency
content_ids
content_type
correctly to Meta.
