Production apps
Delivered across Android, iOS, and web product environments.
I’m Shahriar Asif Rezan, a Bangladeshi mobile app developer focused on Flutter, native Android with Kotlin, and iOS with SwiftUI. I turn product requirements into reliable apps with thoughtful interfaces and maintainable architecture.

My production work spans video streaming, AI fashion, field-service booking, media playback, notifications, real-time chat, payments, GPS, subscriptions, and API-driven interfaces.
I currently develop Flutter products at Betopia Group and previously built native Android applications at E.B Solutions Ltd. That combination helps me choose between cross-platform and native implementation based on the product—not habit.
