Meta Pixel/CAPI + Klaviyo/Calendly Expert

We need an experienced Meta technical specialist to audit and improve tracking and lead funnel performance for a headless Shopify site. Our developer has already implemented Meta Pixel and server-side CAPI, and we need an expert to diagnose remaining issues and collaborate on fixes. Scope includes reviewing event match quality, Pixel and CAPI event coverage, deduplication, event IDs, advanced matching, and purchase data. We also need help sending Meta form leads to Klaviyo, mapping responses for segmentation, exploring secure Calendly prefills, tracking booked vs. non-booked leads, and nurturing leads who submit but don’t book. Please explain how you would approach both the tracking audit and lead funnel workflow.
