I am an expert in creating cross-platform iOS/Android and native iOS apps. While I have a strong knowledge of basics, such as common 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 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. . 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). My wide experience with payment systems allows me to help with choosing the optimal ways for monetization, which leads to increase a company's revenue ?.
