DevShowCase is an Android application designed to showcase my skills as an Android developer.
This project serves as a portfolio for recruiters and technical professionals who want to learn more about my work.
The goal is to build a functional and scalable app using modern Android technologies and best practices.
It incorporates MVVM architecture, design patterns, automated testing, safe navigation, dependency injection, and more.
This project leverages a modern technology stack to ensure quality, scalability, and performance:
- Kotlin: Official language for Android development.
- Coroutines & Flow: For efficient asynchronous operations and reactivity.
- Jetpack Compose: Modern declarative UI framework.
- Material Theme 3: Updated and native Android design.
- Hilt: Dependency injection for modularity.
- Firebase Authentication: Login with Google and Email/Password.
- Firebase Firestore: Cloud storage for favorites.
- Firebase Crashlytics: Error monitoring and crash reporting.
- Firebase Functions (Planned): For backend logic execution.
- Room Database: Offline storage for favorites.
- Retrofit: REST API consumption (GitHub API).
- Paging 3: Efficient paginated list loading.
- Coil: Efficient image loading (GitHub avatars).
- Jetpack Navigation: Safe navigation between screens.
The project follows the MVVM (Model-View-ViewModel) architecture to separate concerns and improve maintainability:
- Data Layer: Repositories, data sources (Firestore, Retrofit, Room), and DTOs.
- Domain Layer: Use Cases encapsulating business logic.
- Presentation Layer: ViewModels and UI using Jetpack Compose.
✅ This approach enhances testability and modularity.
The project includes a robust testing suite to ensure code reliability:
- Unit Tests: Validate business logic in Use Cases and Repositories.
- UI Tests (Compose Testing): Verify UI using Jetpack Compose.
- Instrumentation Tests: Simulate real user interactions.
- MockK: Used for creating mocks in unit tests.
- JUnit: Primary framework for test execution.
These tests help prevent regressions and unexpected issues.
✔️ Login with Google and Email/Password.
✔️ Persistent user session.
✔️ Search GitHub repositories by name or technology.
✔️ Display stars, forks, open issues, and main language.
✔️ Sync favorites with Firestore and Room.
✔️ Show description, main language, commit count, and contributors.
✔️ Open repository in a browser.
✔️ Search GitHub users.
✔️ Display bio, location, followers, and public repositories.
✔️ Toggle between light and dark themes using Material Theme 3.
📌 Phase 1 - Initial Setup
✅ Create GitHub repository.
✅ Configure Kotlin, Jetpack Compose, Hilt, and Retrofit.
✅ Set up MVVM + Use Cases structure.
✅ Configure GitHub API consumption.
✅ Set up Firebase Authentication and Firestore.
📌 Phase 2 - MVP Development
✅ Implement login screen with Firebase Auth.
✅ Implement repository search screen (API + Paging 3).
✅ Implement repository details screen.
✅ Implement developer search screen.
✅ Implement favorites with Firestore (cloud) and Room (offline).
✅ Implement light/dark mode toggle.
📌 Phase 3 - Refinement & Testing
✅ Add Firebase Crashlytics.
✅ Implement unit and UI tests.
✅ Refine UI/UX with animations in Compose.
✅ Implement Firebase Functions for backend logic.
