Native Android Rebuild for NUNU

I need the current NUNU web application (https://nunutech.ai.studio), which was prototyped in Google AI Studio, rebuilt as a fully native Android app. Every feature that exists online today—user roles, dashboards, login and signup flows, data visualisations—must work exactly the same way on the phone while continuing to talk to the very same backend and database that power the site.

You will receive the full source code on GitHub and in a ZIP archive. Use that as a reference for APIs, UI, and logic, but translate the experience into Kotlin/Java inside Android Studio so it feels like a real mobile product rather than a wrapped website.

Key expectations
• Match the current design closely, adding a launch splash screen and proper app icon.
• Keep all authentication and authorisation behaviour intact.
• Ensure dashboards render smoothly on common screen sizes and remain responsive in portrait and landscape.
• Handle network states gracefully—if the device is offline, show a friendly message and retry automatically when the connection returns.
• Thoroughly test every screen and interactive element before hand-over; I will run a final acceptance test on a physical device.

Deliverables
1. Release-ready, signed APK.
2. Complete Android Studio project with clear build instructions.

When you reply, please share similar native Android builds you have completed, a rough delivery timeline, and any questions you need answered before you start.
