Our Stack & Practices

Our app is 100% Swift, built on MVP & Clean Architecture with 35+ independent modules. We use the Coordinator pattern for scalability, and all new screens are built in SwiftUI (MVVM) with async/await — 80+ screens already migrated. Project generation and build optimisation run on Tuist. CI/CD covers GitHub Actions, Bitrise, Firebase Test Lab, Sonar, and Fastlane. We take technical excellence seriously: 30,000+ unit tests, 450+ snapshot tests, SwiftyMocky for mock generation, and LLMs integrated into our dev workflow. Our modular architecture (32 reusable modules + a centralised design system) ensures fast builds, clear ownership, and safe iterations.
