Hey There!!! I'm interested to do your project, I'm good at android project building, I know android development, designing, etc... so I can complete your project faster then other developers can do because they need to wait for the designer to design the application. I have used firebase, recycler view, responsive designing, etc... I use the latest and android studio, the latest SDK, the latest APIs, the latest software, the latest libraries, etc... so you don't need to worry about the new OS, new devices. cost and time will be according to your requirements. need any help, want more, have any problems? just feel free to contact me anytime.
