Hello,
I've excellent skills using react native/ios/Android, Already setup the in-app purchase so many times, I can take care of this for you as well.
I have 6+ years of experience in developing an app for iOS/Android platform(JAVA, Kotlin, Swift, SwiftUI, Objective C along with React native/Flutter app development) and I have developed app for various domains like Social Networking App, News App, Appointment booking App, Education App, Travel App, Health & Fitness app etc.
So I am interested to work on your app as well.
Looking forward to discuss further.
Best regards
