Must have
- Experience: 3+ years of professional mobile app development experience with proven production deployments (not just hobby projects).
- Tech Stack Mastery: Deep, production-level expertise in React Native (ideally with Expo) and TypeScript.
- Live App Portfolio: Must have personally built and shipped live apps currently available on the Apple App Store and Google Play Store (Live store links required during application).
- API & State Management: Strong experience with REST/GraphQL API integration, complex state management, offline data handling, and local storage.
- Mobile Infrastructure: Proven hands-on experience with Push Notifications (FCM/APNs), Deep Linking, and Native Build Tooling (Xcode, Android Studio).

- Language & Soft Skills: Professional working proficiency in English (both written and spoken). Comfortable making independent architectural decisions in a remote team setting.
Nice to have
- Strong eye for mobile UX conventions and native interaction patterns (avoiding a "web app wrapped in a WebView" feel).

- Feature Engineering: Implement deep linking, push notifications (FCM/APNs), user account management, and in-app payments (Apple Pay / Google Pay).
- Media & Interactive Features: Build rich, interactive, media-heavy features including image handling, mobile editors, and real-time data updates.
- Release & Store Management: Fully own the app release process, including versioning, signing, provisioning, Fastlane/EAS Build pipelines, and navigating App Store & Google Play review compliance.
- Performance & Monitoring: Implement mobile analytics, monitor crash reports, optimize app size, and maintain Core Web Vitals/mobile runtime performance.
