Houssem Zaier

Led the migration of the legacy eCommerce Android app to a modular, scalable architecture following Clean Architecture principles to ensure maintainability and growth. Refactored critical components, replacing RxJava with Kotlin Coroutines and Flow to modernize asynchronous processes and improve overall performance. Improved UI and performance by implementing ExoPlayer for video playback and reusable UI components using Jetpack Compose for consistency. Implemented CI/CD pipeline with Bitrise for automation of build, testing, and deployment processes. Collaborated with cross-functional teams to ensure a synchronized and high-performing production environment. Managed networking migration to a Backend for Frontend server and mentored junior developers.
