I have huge knowledge about iOS system and server side applications. As well i have strong experience in computer science, design patterns and standard/analytics/third party frameworks (UIKit, CoreAnimation, MapKit, GoogleMaps, RxSwift, ReactiveSwift, AFNetworkin, AlamoFire and others). I'am preffer automatization and "don't repeat yourself", from coding, testing to app submission. My knowledge in script languages (node.js, python, ruby) allow me to build dummy servers and automate tests for server side application. I'm writing clean code, but can work with old/legacy code, to understand 'how it work' to realize a new feature or refactoring.
