Oleksii K.

Senior Mobile App Developer

I have good understanding of modern mobile applications trends. I always prefer to establish a good communication level with customers to provide exactly what they need and adapt fast to changing requirements. I'm confident, self-motivated and result-oriented person who can work under minimal observation. I can work both efficiently as team player and as an individual. I've built and managed projects for individuals and startups. Business logic, API, database layers are in core project(.net standard library), platform projects are only for data showing and some platforms specific features with native UI and UX guidelines. Xamarin utilizes C# as its key programming language. This enables more than 70% of the code to be reused between iOS, Android and other platforms. An app built with Xamarin offers the same level of performance as that of a natively developed app. Expertise: • More then 5 years experience in software development and mobile development. • Languages: C# • Strong knowledge in Android and iOS SDKs. • Binding Java(.aar) and Objective-C or Swift libraries(CocoaPods) • Native mobile app development for iPhone, iPad, Android phone, and tablet • Creating complex UI iOS(Storyboard, .xib or AutoLayout), Android(XML) • Database: SQLite, Realm • Communication: REST(HttpClient) • Social network integration: Facebook, Twitter, Instagram, VKontakte, Google+, etc • Map integration: Google Maps(iOS, Android), MapKit(iOS) • Analytics services: Google Analytics, Firebase Analytics, AppCenter • CI/CD & Crash Reporting: AppCenter, Firebase • iOS, Android Linker(link all), proguard, r8 • Distribution: Apple Store, Google Play • Design Tools: Sketch, Figma
