Dear hiring manager.
I've just read your project description carefully.
I think the app is very interesting and funny.
If we make it as a mobile app for both iOS and Android, then the app will be loved by many people.
I believe it.!!
And I think asp.net would be not necessary, because all actions could be in mobile device.
So only xamarin will be needed, I think.
I do have a couple of questions, but first I'd like to make you an offer and some background so you can check my work out.
I am a developer with nearly 8 years of experience, with 5 of those years in app development. A lot of the apps I have developed are social apps, so I am pretty familiar with what you need doing.
And xamarin is one of my main skills.
yes, with xamarin we can make apps for both iOS and Android at a time.
I could tell that I can help you with this project.
If the above offer sounds like something you would be interested in, I'd love to hear from you.
Regards
