I'm looking for an experienced React Native developer to implement a robust face liveness check in a mobile app. The flow must open the camera with a circular guide, detect eye-blink (active liveness), and call/run existing C++ code to obtain a passive liveness score (via native bridge / JNI). This is a small, well-scoped feature, but it must be production-quality and work smoothly on Android and iOS. Prefered librires are react-native-image-crop-picker react-native-vision-camera react-native-vision-camera-face-detector
