Hi, I'm
Yousef Dewidar
I build high-performance cross-platform mobile applications with clean architecture and exceptional user experiences.
Turning ideas into production apps.
I'm a Flutter Developer with 2+ years of experience building production-grade cross-platform applications. I specialize in clean architecture, state management with BLoC, and performance optimization — delivering apps that scale across Android, iOS, and web without compromising on quality or user experience.
My work spans from AI-powered platforms like Matgar — an intelligent e-commerce builder SaaS — to official university applications serving thousands of users. I approach every project with a focus on maintainable code, SOLID principles, and responsive UIs that feel indistinguishable from native.

Feedback and thoughts from clients, teammates, and collaborators.
Yousef understood what we wanted from day one. The app feels smooth, our users find it easy to rate and get their cashback, and he always gets back to us quickly when we need a change.

He built the university app in a way that actually makes sense for students — news, schedules, and grades are easy to find without confusion. Very responsive and easy to work with throughout the project.

The app made it much easier for people to keep up with their daily azkar. Yousef really listened to what we needed, the reminders work on time, and the whole experience feels calm and simple to use.

Subscriptions and boarding with the QR code are so much simpler now for both students and supervisors. Yousef got what we needed early on and delivered without us having to explain things over and over.
