Meta Pixel Audit & Implementation

I need a specialist who can jump in quickly, confirm that our Meta (Facebook) pixels are firing correctly, and make any fixes so I can trust the conversion data coming in.

Primary objective
• Track conversions accurately. Retargeting and traffic insights matter, but they come second to reliable purchase / sign-up numbers.

Where the pixels live
• They sit on both a marketing website and our companion mobile app. The web stack was set up before my time, so I’m not 100 % certain whether it’s WordPress, Shopify, or a custom build—please be ready to investigate and adapt.

What I expect from you
1. Audit the current pixel implementation in Meta Events Manager, spotting missing or duplicate events.
2. Configure or reinstall the pixel on web and app as needed, mapping key events (PageView, AddToCart, Purchase, Lead, etc.).
3. Validate through real-time testing and share-screen walkthroughs so I can see the events firing.
4. Deliver a short hand-off document summarising IDs used, code locations, and next-step maintenance tips.

If you’re comfortable working with Meta Events Manager, SDK / CAPI setup for mobile, and common tag tools like GTM, this should be straightforward. Please tell me how soon you can start and roughly how long the audit + fixes will take.
