The solution architecture
Radical Efficiency illustrations
Mobile app with Flutter
Choosing Flutter allowed us to build a high-performant cross-platform app without having to write a different codebase for iOS and Android. This, in turn, helped us to significantly reduce expenses on human resources as we didn't need to establish differently iOS and Android development teams.
Cloud Deployment
We used the GCP App Engine service and Docker to deploy our application. This allowed us to see the first results quickly right after the first week of the app development. The process was performed by one of the developers and didn't require dedicated DevOps engagement at that moment.
