My Unique Expertise
How I practice—scaled delivery, disciplined architecture, bilingual products, and pragmatic ML where it belongs in the roadmap.
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.

Services
How I collaborate with founders, SMEs, hiring teams, and partner agencies—narrow scope lists, clearer delivery.
- 01
Cross-platform mobile apps (Flutter)
Android, iOS, web, and desktop shipped from one codebase with Clean Architecture and BLoC or GetX as the product demands.
- 02
Marketing sites & admin dashboards (Next.js)
Bilingual SSR/SSG layouts, Tailwind-first UI, forms and SEO—when clients need credibility and tooling around the native app.
- 03
REST, Firebase & Supabase integration
Auth—including social providers—notifications, caches, typed errors across large Laravel or Node surfaces.
- 04
UI implementation & bilingual UX
Material 3, RTL parity, spacing and typography tuned for skim-first stakeholders and Arabic-first audiences.
- 05
Performance and maintainability
Structure that survives scope growth: feature modules, codegen where it saves time, pragmatic refactors ahead of milestones.
- 06
ML-aware product features
Pairing Flutter clients with CV/NLP workloads when inference belongs in-product—not slide-deck only.
Projects
Selected case studies from the full portfolio.

Nokta — Ride-Hailing / Delivery MVP
Flutter ride-hailing MVP · Nominatim + OSRM · Offline-first Hive · EN/AR RTL
Context
Ride-hailing MVPs often ship with fake coordinates, brittle map demos, and no offline path—making it hard to swap in a real backend without rewriting core flows.
Contribution
Architected six feature domains with Clean Architecture + BLoC, Nominatim/OSRM maps, Hive offline queue, per-km pricing, and polished MVP UX.
Outcome
Six feature domains (auth, home, trips, notifications, profile, settings) with mock JSON API ready to swap for production backends.

Technology 92 — Employee Management App
Bilingual workforce app · Offline-first handling · Clean Architecture + BLoC
Context
Employees needed one reliable mobile surface for attendance, KPI tracking, onboarding, profiles, and bilingual access while staying resilient when connectivity drops.
Contribution
Built Flutter features with Clean Architecture, BLoC, Dio REST integration, secure token storage, local caching, retry queues, and Arabic/English RTL parity.
Outcome
Unified client covering attendance, KPIs, profiles, onboarding, media/PDF viewing, and settings on one codebase.
