Hi,
I am an expert in creating cross-platform iOS/Android and native iOS apps.
Knowledge of design patterns (MVC, Clean Swift, VIPER, MVVM/RxSwift), programming languages (Swift, Dart, TypeScript, Objective C) and standard iOS frameworks (UIKit, MapKit, SpriteKit, Apple Pay, etc.)
I also have a great experience in the wide number of third-party SDKs: Google Firebase, Facebook, PayPal, Stripe, Google Maps, ad networks, Parse Server, etc.
My backend experience is in Google Firebase. Using Google Cloud Firestore as a database and Firebase Cloud Functions written on TypeScript I can easily create a robust backend for mobile and web apps.
In 2019 I started to move to cross-platform development using Flutter/Dart.
I'm also familiar with implementing in-app payments, like In-App Purchases and subscriptions, Apple Pay, PayPal and Stripe SDKs (both client-side and server-side).
I can guide through the Apple app review process to make it smooth and avoid any rejections.
Please share the details of the app so that I can review them and estimate the approx time to complete them in a better way.
Best,
Pradeep
