Development of a cross-platform mobile application using React Native (Expo) for iOS and Android. The app is built on a secure architecture connected to a REST API protected with OAuth2, enabling the management and synchronization of server-configured events.

Implementation of a geofencing system linked to these events, allowing the application to trigger actions or notifications based on the user’s location in real time.

Integration of a local caching layer to improve performance, reduce network requests, and ensure a smooth user experience even in low or unstable connectivity conditions.
