I've built and maintained Flutter and Dart applications at Code7X, delivering scalable Android and iOS releases from planning through deployment.

I own mobile feature delivery across the SDLC, using Clean Architecture, modular code structures, Dio, and REST APIs to support maintainable products.

At By Bus, I delivered passenger and driver apps through Play Store and App Store launch, including real-time location tracking, trip management, WebSocket, and Google Maps SDK integrations.

Across Innova-Digits, MolTaqa, and IX Solutions, I've shipped cross-platform features, improved performance and stability, and worked closely with backend, design, and QA teams.
