Hello,
I am very interesting in your project fixes and updates, so I can quickly and easily implement all features that you want, because I have a big experience in Android, and of course I've already worked on all that features, that you listed in the project description. You can check my portfolio, most of my apps have some features, that you listed.
It's not so complicated, so I think I can do this very fast. And of course I guarantee you will have a daily review of the work done. Maybe it will be time-saving. It's very interesting for me, because I love Greece and all that's connected with it.
I hope we will be a good partners. Thank you!
