    Sample input

    I'm building a React Native fintech app. I need an offline sync strategy and a security audit checklist for handling sensitive transaction data.

    Sample output

    Offline Strategy: Use WatermelonDB for local persistence with a Delta Sync protocol.

    Security Checklist:

    • Enable SSL Pinning via react-native-ssl-pinning.
    • Store JWTs in Keychain/Keystore (use react-native-keychain).
    • Implement biometric fallback for high-value transactions.

    About This Skill

    From architecture decision to App Store approval: this skill covers the full native and cross-platform mobile stack. Designs the app architecture (SwiftUI, Jetpack Compose, React Native or Flutter), patterns offline sync and local-first data, implements push notification and deep-link structures, audits for performance and security issues that cause App Store rejections, and generates metadata optimised for App Store search. Returns an Architecture Decision Record, screen flow specification, submission checklist, and ASO keyword strategy. Specify platform, target audience and key features — saves you the rewrite that most apps need after v1.

    Use Cases

    • Design robust offline-first architectures for intermittent connectivity.
    • Navigate complex App Store and Google Play submission requirements.
    • Develop secure state management for fintech and healthcare applications.
    • Optimize mobile app performance and battery consumption across platforms.
    • Establish automated CI/CD pipelines specifically for mobile build targets.
