@zahidhasan4
Mobile application developer specializing in cross-platform Flutter apps with 2+ years experience.
What I'm looking for
I’m a Mobile Application Developer focused on cross-platform apps built with Flutter and Dart. I design responsive, pixel-perfect interfaces in Figma/Adobe XD and turn them into clean, maintainable code while integrating REST APIs and WebSockets for seamless user experiences.
Since August 2023, I’ve been building and shipping production mobile apps at Codixel using Flutter, GetX/Provider/Riverpod/BLoC, and a strong testing approach (unit, widget, and integration tests). I’ve optimized frontend performance across different screen sizes and helped maintain 99%+ crash-free user sessions, with deployments to Google Play Store and Apple App Store.
My work includes advanced features like chat boot, audio streaming, online exam modules, in-app purchases, and sslcommerz-bkash payment, plus Firebase features such as Remote Config and real-time updates. I also delivered live projects like Earnings Call (audio player with transcript, WebSocket chatbot, A/B testing, GCP logging), LawEntra (SSLCOMMERCE payments and exam prep platform), and MyDo (offline-ready task and reminder app with push notifications).
