Corporate Resource Booking System
An enterprise-grade mobile application for managing shared corporate resources with real-time availability tracking and automated conflict detection.
Use Cases
Employees can browse available corporate resources organized by categories (Rooms, Desks, Equipment, Vehicles), view detailed resource information including capacity, location, and amenities, and check real-time availability through an intuitive hourly time slot grid (8 AM - 5 PM). The system displays busy time slots visually, preventing users from selecting unavailable periods. Users can create bookings by selecting a date and hour slot, with automatic conflict detection ensuring no double-bookings occur. The application provides a personalized dashboard showing upcoming bookings, recent activity, and quick access to frequently used resources. Users can manage their bookings by viewing all reservations, canceling upcoming bookings, and tracking booking status (Upcoming, Completed, Cancelled). Administrators have additional capabilities to manage resources, view user statistics, and access admin panels for comprehensive resource management. Perfect for corporate offices, co-working spaces, event venues, and organizations requiring efficient shared resource allocation with real-time synchronization and mobile accessibility.

Architecture
Built with a mobile-first architecture using React Native (Expo SDK 54) for cross-platform development, enabling native iOS, Android, and web deployment from a single codebase. The application follows a component-based structure with React Navigation for stack and tab navigation, implementing context-based state management (AuthContext, ThemeContext, LanguageContext) for global application state. The backend leverages Firebase Firestore for real-time document storage with optimized queries using composite indexes, Firebase Authentication for secure user management with role-based access control, and Firestore Security Rules for comprehensive data protection. The frontend uses React Native components with Expo modules (BlurView, LinearGradient, DateTimePicker) for native mobile experiences, while React Native Web enables seamless web deployment. The architecture implements real-time listeners (onSnapshot) for live booking updates, automated conflict detection through Firestore queries, and efficient data fetching with proper indexing. The design system uses custom theme tokens (colors, typography, spacing) with dark mode support, and the application includes internationalization (i18n) with support for multiple languages. This architecture enables scalable resource management, real-time synchronization across all clients, and supports future features like push notifications and calendar integration.
Security & Performance
Security is implemented through Firebase Authentication with email/password authentication, JWT-based session management, and role-based access control (User/Admin) with Firestore Security Rules ensuring users can only access and modify their own bookings while admins have full resource management capabilities. The system includes comprehensive Firestore Rules validation preventing unauthorized data access, ensuring booking creation requires authenticated users, and allowing booking cancellation only by the owner or administrators. Error handling includes user-friendly error messages for authentication failures, network errors, and booking conflicts. Performance is optimized through Firestore composite indexes for efficient queries combining userId and startTime filters, enabling fast booking retrieval even with large datasets. The application implements real-time listeners with proper cleanup to prevent memory leaks, uses efficient data structures for time slot calculations, and implements client-side conflict detection before server submission to reduce unnecessary API calls. The mobile-first design ensures optimal performance on native devices with smooth animations using React Native Reanimated, while web deployment uses React Native Web for consistent behavior across platforms. The system handles timezone conversions properly, implements efficient date/time parsing, and uses memoization for expensive calculations.
Development & Deployment
The application is built using Expo SDK 54 with React Native 0.81.5, enabling development across iOS, Android, and web platforms from a single codebase. Development workflow uses Expo CLI for local development with hot reloading, Expo Go for mobile testing, and web support for browser-based development. The codebase follows React Native best practices with functional components, React Hooks for state management, and proper component lifecycle management. The frontend is structured with a modular architecture separating components, screens, navigation, services, and context providers. The application includes comprehensive internationalization (i18n) with support for English, Polish, and Spanish, implemented through a LanguageContext with translation functions. The design system uses custom theme tokens with dark mode support, implemented through ThemeContext with system preference detection. For production deployment, the web version is built using Expo export with static file generation, served through an Express.js server for Railway deployment. The deployment uses Railway's Railpack builder for automated builds, with environment-based configuration for Firebase credentials. The application supports responsive design with a fixed mobile resolution (390x844px) for consistent web experience, and includes proper error boundaries and loading states throughout the user interface. The entire system supports automated CI/CD through Railway with GitHub integration, enabling automatic deployments on code pushes.
