Module Architecture

The project uses a multi-module architecture with convention plugins for consistent build configuration:

• Convention Plugins: gizmo.kmp.library, gizmo.compose, gizmo.feature, gizmo.koin.ksp
• Core Modules: Shared infrastructure used by all feature modules
• Feature Modules: Self-contained features with their own domain, data, and presentation layers
• App Module: Aggregates all modules and provides platform-specific entry points

Features

• Track poker sessions with detailed statistics
• Multi-platform support (Android, iOS, Desktop)
• News feed with poker articles and strategy content
• User authentication with JWT
• Offline-first architecture with SQLDelight
• Type-safe database queries with jOOQ
