What I'm looking for

I'm looking to own secure, scalable Flutter products end-to-end, collaborate closely with Agile teams, and contribute to clean architecture, performance, mobile security, and technical leadership.

I've built Flutter products at JATDEV Middle East, including SpaceJat, a secure Arabic collaboration platform with real-time messaging, audio and video calls, webinars, screen sharing, and secure file storage. As the company’s first Flutter developer, I took Flutter projects from the ground up and helped build and lead the Flutter team.

Previously at Knowledge Object Bonds and AwareBox, I improved API data-fetch time by 30%, reduced crash rates by 50%, optimized app size by 20%, built Android and iOS interfaces, integrated payment gateways, and launched apps on Google Play and the App Store. I focus on Clean Architecture, state management, CI/CD, mobile security, and dependable end-to-end delivery.
