MD. Shahriar Asif Rezan

Flutter, Android (Kotlin) & iOS (SwiftUI) Developer
Betopia Group (March 2025 – Present)

Delivered 10+ production apps across Android, iOS, and Web using Flutter, Kotlin, and SwiftUI.
I specialize in Flutter with Provider and Riverpod for state management and have strong experience integrating REST APIs and WebSocket for real-time chat apps. I’ve also implemented Firebase Cloud Messaging (FCM) for push notifications, Google and Facebook Authentication, and payment systems like Stripe and bKash. I also have hands-on experience with native Android (Kotlin/Java) and iOS (Swift) development, ensuring smooth performance across both platforms.
