Hi, I’m Mohamed Boumlyk, Senior Android Developer focusing on secure, efficient, scalable apps. I build in Kotlin/Java using MVVM/MVP, Hilt, and Coroutines. I create UIs with Jetpack Compose/XML, manage data with Room and EncryptedSharedPreferences, and secure network calls via Retrofit/OkHttp (TLS pinning). Experienced with Firebase (Auth, Firestore, Analytics, Crashlytics), Play Billing, Maps, WorkManager, and AccessibilityService. I deliver modular code and implement Keystore/biometric security, code obfuscation, root detection, thorough testing with JUnit/Espresso, and CI/CD pipelines.

He was able to quickly integrate the camera feature and the photo editing feature into the Kotlin app and fix a few stubborn bugs. I’d be happy to work with him again.
