Aleksandr S.

Android developer

Hi! I’m an Android developer with 6+ years of experience building apps across different domains — from e-commerce and fintech to IoT and crypto wallets. I’ve worked both with large-scale products (up to 14M+ users) and MVPs from scratch, so I know the full development cycle inside and out. Over the years, I’ve tried pretty much every modern technology used in Android today — Jetpack Compose, KMM, WorkManager, CI/CD, analytics, and more. I focus not only on delivering features but on building solid, scalable solutions. I care about clean architecture, performance, and developer-friendly code. Skills and Expertise: • Kotlin, Java, Android SDK • Jetpack Compose, ViewModel, LiveData, Room, WorkManager • MVVM, MVI, Clean Architecture • DI: Hilt, Dagger, Koin • Сетевые библиотеки: Retrofit, OkHttp, Ktor • KMM, Firebase, Google Analytics • CI/CD (GitHub Actions, Bitrise) • Jira, Trello
