Hi,
I understood that you want to build an android app where the backend is built-in wp by you
Can you please send me more details about app features/screen design to review. I can develop it for you.
I have 7+ years of experience with mobile app development and have developed many native & hybrid mobile apps. Please my profile / come to chat to show you some of app work, I have done.
Waiting to hear from you soon. I can start the project immediately.
Sincerely,
Jigar
