Engineering
We still see products where the website talks to the database directly and the Android app is an afterthought. That split always shows up later as duplicated logic and inconsistent validation.
The cleaner path is a documented REST API with authentication, consistent error shapes and a staging environment both teams can hit.
Minimum API hygiene
- Token-based auth
- Validation on the server, not only in the UI
- Versioning when you break contracts
- A written list of endpoints the mobile team can trust
Do this early and every later screen becomes cheaper.
