I’m Mostafa Abd Elalim, a cross-platform Flutter developer with 2+ years of experience building and shipping reliable applications for Android, iOS, Web, and Windows. I focus on clean architecture, a smooth user experience, and delivering features end-to-end—from UI implementation through release—using practices like Clean Architecture, MVVM, and CI/CD. I’ve delivered 20+ production apps, including offline-first POS flows and enterprise SaaS solutions. I work with offline data handling (SQLite/Hive with sync and reconciliation logic), REST APIs and GraphQL, and Firebase tools such as Auth, Firestore, Cloud Functions, FCM, and Crashlytics—while continuously improving performance through profiling and optimization, including measurable reductions in client-side network latency.…I’m Mostafa Abd Elalim, a cross-platform Flutter developer with 2+ years of experience building and shipping reliable applications for Android, iOS, Web, and Windows.
