Authentication designed for mobile sessions
Token-based authentication that survives app restarts and works across spotty connectivity — a different pattern than typical web session cookies. See API & Backend Development for the general backend discipline this sits within.
Data sync and offline handling
A mobile app frequently needs to work with intermittent connectivity — deciding what syncs immediately vs. what's queued for the next connection is a real architecture decision, not an afterthought.
Push notification infrastructure
Server-side infrastructure to trigger and target push notifications correctly (per user, per platform) — distinct from the client-side permission handling on the app itself.
API design independent of frontend framework
The same backend/API can serve a native iOS app, a native Android app, a React Native app, or a PWA — designing it well once means the frontend platform choice (see PWA vs Native vs Cross-Platform) doesn't require rebuilding the backend.
Questions
Does the backend change if we choose React Native vs. native?+
No — a well-designed backend/API serves any frontend framework; the framework choice affects the client, not the backend.
How is mobile authentication different from web?+
Mobile typically uses token-based auth designed to survive app restarts and intermittent connectivity, rather than typical web session cookies.
Can LATYNEX build just the backend for an app being built natively elsewhere?+
Yes — this is a common, standalone engagement, independent of who builds the native frontend.
