Mobile with backend and operations included

An app does not end at the store. It includes API, release, crash measurement, and a maintenance plan.

•Cross-platform with Flutter, React Native, or Expo; native with Swift (iOS) and Kotlin (Android) when the case calls for it.
•Integration with backends and APIs (ours or existing).
•App Store / Google Play publishing and release pipelines.
•Analytics, crash reporting, and ongoing maintenance.

What we build
