Our stack & quality practices
Our app is 100% Kotlin, built on MVVM & Clean Architecture principles. We leverage the Coordinator pattern, Coroutines, and Flows to ensure a robust and scalable codebase.
We are committed to a modern UI: all new screens are built with Jetpack Compose, and we have migrated 85% of our legacy views.
Our CI/CD pipeline includes GitHub Actions, Firebase Test Lab and Sonar.
We prioritize technical excellence by:
• Strictly adhering to Clean Code / SOLID principles to maintain an healthy codebase
• Investing heavily in stability & tests: with 26k+ Unit Tests, 14k+ Snapshot test, and 500+ UI Tests.
• Adopting a module-based architecture: We have moved away from a monolith to ~1000 modules (1.2M LoC), ensuring faster builds, clear ownership, and safer iterations.
• Following a component-driven approach for UI consistency and reuse.
