Hello
my name is Julius Huck and I m a developer from Germany.
I m a C# programmer with a very good knowledge of XAML.
I will create these Apps with Xamarin Froms and Xamarin Android. So when you want I can compile them for IOS or Windows Phone too.
(In Xamarin you can create a single C# code base and then you can compile your app to every platform. And when there is some platform specific code you can do that effortless too. So with the new .NET standart concept of Microsoft this is the modernst oportunity to create Apps today)
I know how to program every app in your list. (All for Android, For the other platforms I have to look some things up)
They will all have a good look and a nice and userfriendly UI. I will document the code very good, so you or I can add features to the apps later too.
Looking forward to work with you.
Julius
PS: Why are skills like php and html and so on requierd. I thought the Apps should be Android Apps. And Android Apps are programmed in Java, Kotlin or in C#. You can program html apps which will run on Android but they are looking ugly and don t have a good userexperience...
