At Arashnia, I led development of an English learning app from scratch, reaching 300K+ installs and 10K+ daily active users. I designed features with Kotlin and Java, using MVVM and Clean Architecture.

I improved the app’s security with JNI/NDK encryption and customized ExoPlayer for video playback. I also mentored junior developers and coordinated releases.

At Lingua, I built an Android app with Kotlin, Jetpack Compose, and MVVM. I implemented Firebase services and Google Sign-In, and designed custom animations.

At ArmenGo, I architected a multi-module Android app with 80%+ code reuse between User and Admin applications. I developed offline-first synchronization and automated build distribution to Google Play Internal Testing and Telegram QA channels.
