GA4 / GTM / Meta Pixel / Conversions API Tracking Expert Needed for Conversion Tracking Audit + Fix

We are looking for a sharp analytics and paid media tracking specialist to audit, repair, and document our conversion tracking setup across GA4, Google Tag Manager, Meta Pixel, and Meta Conversions API. We are a fintech/sports startup where fans invest in the careers of top baseball prospects. Our paid acquisition funnel includes account creation, investor onboarding, checkout, and completed investments. We need someone who can make sure our tracking is accurate, clean, and reliable before we scale ad spend. We previously had someone helping with GA4, tracking, and Meta ad conversions, but they disappeared mid-project. So this project starts with an audit of the existing setup and ends with a clean, documented tracking system that we fully own.
