Contributed to the devlink-community/gaesubang-app by architecting and implementing core features for group management, onboarding, and map integration over two months. Leveraged Dart and Flutter to establish a scalable domain layer with clean architecture, dependency injection, and robust state management using Riverpod. Developed end-to-end group lifecycle flows, reusable UI components, and integrated Naver Maps for location features. Enhanced user experience through onboarding flows, theming, and UI/UX refinements, while maintaining code quality with extensive refactoring and bug fixes. Automated documentation and issue management workflows using GitHub Actions, improving onboarding and maintenance. Addressed technical debt through systematic code cleanup and modularization.
In May 2025, delivered a substantial foundation and scope expansion for the Group domain and related UI, routing, and map capabilities in the devlink-community/gaesubang-app. Established a scalable domain layer (model, DTOs, mappers, repository interfaces and data sources) with end-to-end use cases (create, read, update, join/leave), and wired dependency injection for clean architecture. Built user-facing Group features including List screen, detail navigation, create flow with image picker and platform permissions, and group search, plus reusable UI components (LabeledTextField, TagInputField) to accelerate future work. Implemented Group Settings and Group Search scaffolds with state/notifier patterns, and introduced consistent style and theming across the app (Styleguide refactor, Roboto font, dark mode). Added map capabilities with geolocator/datasource scaffolding and initial Naver Map progress, alongside onboarding flow and splash screen. Improved routing stability with router merges and bug fixes to prevent regressions, and completed a broad cleanup pass (DTO/mapper renames, import path fixes, pubspec.yaml updates) to reduce technical debt and improve maintainability.
