RevenueCat Expert: Subscription Architecture, Global Matrix Config

We are seeking an expert RevenueCat Implementation Specialist to architect and configure the complete in-app purchase and subscription backend for our mobile application, Retain Quran. Our monetization strategy is highly sophisticated and built around a Purchasing Power Parity (PPP) adjusted framework spanning 9 global regions, utilizing custom native UI paywalls triggered by in-app user milestones. We have mapped out an 81-SKU matrix (consisting of Tier 1, 2, and 3 options for Monthly Subscriptions, One-Time Purchases, and Monthly Upsells per region). We need a dedicated RevenueCat veteran who can step in, look at our pricing spreadsheet, and flawlessly construct our offering architecture inside RevenueCat without us making costly structural mistakes. Scope of Work RevenueCat Project Architecture: Translate our 9-region pricing spreadsheet into a clean, scalable structure of Entitlements, Offerings, and Packages inside RevenueCat. Google Play Console Linking: Handle the end-to-end API configuration, financial permissions, service account credentials, and JSON keys required to link our Google Play Console to the RevenueCat dashboard. Metadata & Dynamic Paywall Configuration: Configure custom JSON attributes and metadata on products within RevenueCat so our mobile developers can dynamically style our custom Figma UI and update our dynamic impact formulas directly from your dashboard. RevenueCat Native Integrations: Configure RevenueCat’s out-of-the-box integrations (Mixpanel and Google Analytics) to ensure all subscription, renewal, and cancellation lifecycle events flow perfectly into our analytics. A/B Testing (Experiments) Setup: Construct our initial pricing experiments within RevenueCat Experiments so our product team can split-test tiers and layouts without requiring future app updates. Required Technical Expertise Deep, proven track record setting up and managing complex configurations strictly within RevenueCat. Expert-level understanding of the Google Play Console billing backend, store regions, subscription lifecycles, and sandbox testing. Experience utilizing RevenueCat’s Product Metadata/JSON payload feature to drive dynamic, server-controlled custom client-side app paywalls. Solid understanding of RevenueCat's native webhook data structures and its platform integration marketplace. How to Apply Please outline your direct experience with RevenueCat.
