Position: Android developer, iOS developer
Category: Android
English level: upper
Years of experience: 4

One week I have been worked about 80 hours per week, when we really need to make something fast

Made hot (part by part with new feature development) replacement legacy code to modular, flexible, modern architecture (LiveData + MVVM)

Made UIKit with all stored styles and view components, which allow to easily modify some style or logic inside components

Working with android firmware (rewrite small parts in C++ for internal usages)
Has experience with:
1. Android: 
- Custom animation with really impressive charts and data visualisation
- A lot of Android SDK (WiFi, Camera, Bluetooth, AlertManager etc) 
- Video streaming with encode / decode, ONVIF familiar
- Different API (RESTful, GraphQL, JSON-RPC, WSS)
- Different architecture (MVP, MVVM + Clean architecture)
- CI (Gitlab-CI, Jira Bamboo)
- Zeplin Style guide (UIKit for several project with one library)
- Kotlin Coroutines in production
2. iOS: 
- Different API (RESTful, GraphQL, WSS)
- Architecture MVP, MVVM + Clean architecture (VIPER)
- Fastlane (from CI build to App Store delivery)
- RxSwift
Could support both platforms with same expertise (working with iOS in parallel), this give consistency of behaviour.
Like to try Kotlin-Native.
Want to make my own schedule (of course, excluding important issues).
