I am an expert in creating native iOS apps, Android apps and dynamic websites. While I have a strong knowledge of basics, such as common design patterns i.e. MVC, Clean Swift, VIPER, programming languages i.e.Objective C, Swift, Python, PHP and standard iOS frameworks i.e. UIKit, MapKit, SpriteKit, Apple Pay etc). I also have a great experience in third-party SDKs: Google Firebase, Facebook, PayPal, Stripe, Google Maps, ad networks, Parse Server etc. 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). 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 ??. I can guide through Apple app review process to make it smooth and avoid any rejections. Contact me with your iOS, Android app or website idea to start the engagement process.
