Our tech stack and architecture
You will work with a modern, scalable application architecture:
- Flutter & Dart: For building cross-platform applications for mobile and web.
- Serverpod: Our Dart-native backend-for-frontend, enabling full-stack Dart development
- Clean Architecture: A layered package structure with a strict dependency flow, keeping UI, application logic, domain, and data layers strictly separated.
- MVVM with Stacked: Viewmodels, Commands, and Reactive values for predictable state management.
- Mason CLI: We use code-generation templates for standard components and patterns to ensure standardization and reduce boilerplate code.
