Hello
How are you?
I am an individual experienced developer having more than 6 year of experience in mobile application development (4 year in Native IOS and Native Android & 2 year in Flutter(iOS and Android)).
During this period of time I have uploaded 200+ apps on app store.
I will upload your app on apple store successfully, I have good knowledge of distribution certificate, provisioning profile, appid, apple guidelines etc etc.
I need working source code and paid apple developer account other things I will take care myself.
Thanks
