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.
In 2019 I started to move to cross-platform development using Flutter/Dart.
The work I provide is of the highest quality, fully responsive, and tested in a wide range of devices. I take great care to ensure each project is well-architected, well-documented and easily maintainable so you can enhance an app as your company grows.
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).
