About

I’m Mostafa Samir, a Flutter Developer and Mobile Application Engineer from Egypt, focused on building cross-platform mobile apps with Dart and Flutter. I enjoy turning ideas into clean, responsive UI, integrating APIs and Firebase features, and improving app performance through thoughtful architecture and debugging.

I’m also experienced with state management (Bloc/Provider/Cubit), clean architecture and MVVM patterns, and I like collaborating with designers and backend engineers to deliver reliable features. Alongside my development work, I lead and mentor on Flutter projects, and I use AI-assisted tools to speed up implementation, streamline troubleshooting, and keep code maintainable.
