Mobile quality is felt in the seams
Users notice when navigation hesitates, forms lose state, permissions appear without context, releases behave differently by environment, or the mobile flow disagrees with the backend. React Native is most effective when those seams are treated as product architecture, not late-stage polish.
The work extends beyond the component tree
Release environments, secrets, build variants, and store constraints need deliberate ownership.
Offline, loading, error, and retry states must match the importance of the user action.
APIs should support mobile latency and lifecycle realities instead of assuming a stable desktop session.
Shared code earns its place only when it improves consistency without flattening platform-specific experience.
