Bron24 is a mobile app for booking football stadiums across Tashkent, Uzbekistan.

This was a team project initiated in July 2024. I initially built the Android client from scratch and later collaborated with a second developer. This README document outlines the MVP version and lessons learned from the development process.

• OTP Authentication via phone number
• Stadium listing with filter and search
• Stadium detail view with images, location, and schedule
• Booking flow (backend confirmation, no payment integration yet)
• View current and past bookings
• User profile management
• Interactive map using Yandex Maps
• Multilingual UI: English, Russian, Uzbek

• Clean Architecture: split into presentation, domain, data layers
• MVVM initially, then partially migrated to MVI with Orbit MVI and Voyager Navigation
• Followed SOLID principles
• ViewModel + StateFlow for reactive state management
• Navigation Component and later Voyager for screen routing
• Dependency Injection via Hilt

Key reflection: logic started leaking into UI and repository layers. More architecture maturity leads to cleaner, abstracted domain logic.

• Jetpack Compose (first production use – declarative and clean)
• Kotlin Coroutines & Flow (reactive and concise)
• RESTful API integration
• Chucker for HTTP debugging
• Custom UI based on Figma designs (not using Material Design system)

• Over-engineered MVP: focused too much on “doing it right” rather than “shipping it fast”
• Missed sync points with backend & iOS team
• Kanban process lacked flexibility in Trello (originally used ClickUp)
• Time wasn't allocated for testing and CI/CD integration

• Add local cache with Room DB
• CI/CD with GitLab Pipelines
• Firebase Crashlytics setup
• Dark theme support
• Google Play release (we reached Beta Test stage)
• Online payment integration (Click / Payme)

• It’s OK to simplify features, but not architecture
• Jetpack Compose needs performance mindfulness (recompositions matter)
• Coroutines are powerful but easy to misuse without understanding the internals
• The architecture you build reflects your "pattern recognition" across projects

If you're curious about building apps with Clean Architecture or Kotlin Compose workflows, this repo is a practical showcase with real-world lessons.
