This is a cross-platform mobile development skill focused on React Native and Flutter, handling everything from native module integration to offline-first architectures. You'd reach for it when building iOS and Android apps simultaneously, implementing complex native features like Bluetooth or biometrics, or setting up mobile CI/CD with tools like Fastlane and EAS. It's passed security audits from Gen Agent Trust Hub, Socket, and Snyk, and has 128 installs with 76 GitHub stars. The skill explicitly covers performance optimization work like reducing startup time and bundle size, plus it handles the migration path if you're moving a web app to mobile. Solid choice if you need someone who speaks both the React Native and Flutter ecosystems fluently.
