Development and Shipping: Built and shipped a React Native Expo app end to end, from features and release pipeline to App Store and Google Play submission, reaching 100k+ downloads in under 1 month. Ad Monetization: Owned the full AdMob stack, including ad placements, multi network mediation, mediation tuning, and eCPM floors, driving ad revenue well beyond a single network setup. Firebase: Used Firebase end to end with Cloud Functions for sensitive logic, keys, and validation, App Check for API security, plus Firestore, push, Remote Config, and Analytics. Optimized queries and caching to keep cloud costs low at scale. Subscriptions: Built RevenueCat subscriptions and in app purchases with region based pricing and offers, reliable entitlement sync, and hands on support for billing, restore, and purchase issues.
