Ansar Zafar

Senior Android Developer with 6+ years of experience building scalable, high-performance native applications using Kotlin, Java, and Jetpack Compose. Skilled across the full app lifecycle — architecture (MVVM/MVP, Clean Architecture), dependency injection (Hilt/Dagger), asynchronous programming (Coroutines, Flow), local persistence (Room), REST API integration, and Firebase services. Experienced leading developers, mentoring junior engineers, and owning releases through Google Play Console with CI/CD pipelines (Git, Bitbucket).

Comfortable working with distributed, English-speaking teams across time zones.
