I'm a Computer Science graduate from Nile University specializing in Flutter mobile development. I turn designs into polished, responsive apps — built with clean architecture, BLoC, and offline-first patterns, and delivered through internships, freelance work, and apps published on Google Play & the App Store.

What sets me apart.

Cross-platform product delivery

End-to-end Flutter builds for Android, iOS, web, and desktop with Material 3, responsive layouts, and release-ready structure informed by production client work.

Clean Architecture & BLoC at scale

Feature-first layering (domain, data, presentation), BLoC/Cubit, routing with go_router, and DI patterns that stay maintainable across large API surfaces.

Production APIs & bilingual UX

Dio-backed REST integration, auth flows including social sign-in, notifications and background work, plus Arabic/English UX with intl/ARB and full RTL support.

ML integration in mobile apps

Bridging computer vision and NLP prototypes with Flutter clients—emotion analysis, facial recognition patterns, and research-driven features aligned with coursework and graduate project direction.
