AlarmBoard Flutter App

Architect / CEO Founder Flutter Kotlin AWS ...
Architect / CEO Founder

AlarmBoard is a mobile app for Android and iOS designed to track staff during emergency operations and manage an emergency organization like a fire brigade. Since 2019, my fire brigade has been using AlarmBoard to monitor our staff and operations.

Over several years, I?ve tested new implementations and architectures in the app as well as in the cloud using AWS. The app served as a playground for my development growth.

In early 2020, my teammates joined me, and we began testing Flutter.

I?ve handled all the architectural work for the app and backend and guided my colleagues through the development process.

Thanks to the app?s layered architecture, we could easily exchange some layers using Flutter. In mid-2020, we dropped all Kotlin code and switched to 100% Dart.
