App Conversion Tracking Expert (Google Ads + Firebase/GA4)

We are looking for a senior Google Ads / Firebase / GA4 expert with strong experience in mobile app conversion tracking and Google ads App Campaigns. We already have: * An Android app * Firebase Analytics implemented * GA4 connected * Google Ads connected to GA4/Firebase * A custom in-app event for a successful user action * Google Ads campaigns running and optimizing this event However, we have a serious discrepancy in the data. During a recent campaign: * Google Ads reported approximately 3,000 conversions * Firebase / Google Analytics reported only approximately 400 actual events This caused the campaign to spend significantly more than expected, while the actual number of users completing the intended action was much lower. What we need We want to arrange a live screen sharing video call with: * Me * Our app developer * you ( The Google Ads/Firebase expert) During a live screen-sharing call with me and our developer, we need you to review the full Google Ads + Firebase/GA4 conversion setup, identify why Google Ads reported around 3,000 conversions while Firebase/GA4 showed only around 400, and fix the setup with us. You should be able to check the event implementation, conversion settings, campaign goals, attribution, and whether Google Ads is counting or optimizing for the wrong actions. The goal is to understand exactly what caused the discrepancy and configure the tracking correctly so future campaign reporting is reliable and as closely aligned as possible across Google Ads and Firebase/GA4. Payment is after new test with correct results.
