I led frontend across all three surfaces: a 64-route React Native customer app for iOS and Android at roughly 38k lines and 154 components, a companion Next.js web portal, and a staff admin panel.
- JWT access and refresh tokens held in the device Keychain and Keystore
- Single-flight refresh interceptor, so concurrent 401s share one refresh rather than stampeding
- Biometric session unlock and trusted-device sign-in
- Web portal scoped deliberately narrower than the app, to drive mobile adoption
