Mobile Application .NET MAUI - Android - iOS

I want to build an Android mobile application using .NET MAUI and C#.

Note : I will build the application myself. I just need someone to guide me through the process, track my progress, and tell me what to do and how to do it step by step. I don’t want anyone to build the application for me. I only need support and guidance until the application is fully completed, tested, and uploaded to the app store.

The application will connect to a backend system through an ASP.NET Core Web API.
It should work offline using a local SQLite database when there is no internet connection.
When the internet becomes available, the application should synchronize local data with the server automatically.
The application should use secure login with Two-Factor Authentication (2FA).
It should also include a map that can display locations and application data.
The map must support offline use, including previously downloaded map areas and locally stored points.
and in the end need upload it on the stores Apple and Google
