Ahmed H.

Android developer with deep focus on Kotlin and MVVM architecture — building apps designed for maintainability, not just shipping features. My work includes Firebase-backed systems with security-rule-enforced data isolation, Repository-pattern abstraction over REST APIs, and reactive UI state via LiveData. Core skills: MVVM & MVP architecture, Firebase (Firestore, Auth, Cloud Sync), Retrofit & Gson, Room, Coroutines, RecyclerView/Adapter patterns, and Material Design. I debug from raw network payloads up, not from assumptions — and I document what I build.
