Project Overview
From May to July 2018, I served as the Lead Developer for Winston UTrack, a comprehensive educational workshop management application. This freelance project involved developing a cross-platform mobile solution that successfully launched on both Google Play Store and Apple App Store, demonstrating significant impact with 130+ student sign-ups on launch day.
The project required full-stack development expertise, combining React Native mobile development with Ruby on Rails backend architecture. I was responsible for the complete technical implementation, from designing the user authentication flow to building dynamic scheduling features and ensuring seamless data management across all platforms.
Launch Success Metrics
Technical Implementation
Authentication & Navigation System
Designed and implemented a comprehensive authentication flow using React Navigation, ensuring a seamless and secure login experience across the mobile application. The system provided robust user session management with secure token-based authentication integrated with the Rails backend.
- React Navigation: Implemented stack and tab navigation with authenticated route protection
- Secure Authentication: Token-based login system with automatic session management
- User Experience: Seamless onboarding flow with persistent login state
- Cross-Platform: Consistent authentication behavior across iOS and Android
State Management & Performance
Optimized global state management by leveraging Redux architecture, ensuring efficient data flow and consistent application state across all components. This implementation provided scalable state management for handling workshop data, user sessions, and real-time updates.
- Redux Architecture: Centralized state management with predictable state updates
- Optimized Performance: Efficient data flow reducing unnecessary re-renders
- Scalable Structure: Modular reducers and actions for maintainable codebase
- Real-time Sync: Consistent data state across navigation and API calls
Dynamic Schedule Management
Built a dynamic schedule page using FlatList, mapping real-time workshop data into structured timetable slots. This feature provided students with an intuitive interface to view and manage their educational workshop schedules with smooth scrolling performance.
- FlatList Implementation: Optimized list rendering for large datasets with smooth scrolling
- Real-time Data: Dynamic workshop information with automatic updates
- Structured Layout: Organized timetable slots with clear visual hierarchy
- Interactive Design: Touch-friendly interface optimized for mobile interaction
Backend Architecture
Integrated PostgreSQL with a Ruby on Rails API-only backend, ensuring scalable student and workshop data management. The backend architecture was designed to handle the successful launch day traffic of 130+ student sign-ups while maintaining data integrity and performance.
Backend Implementation
- Ruby on Rails API: RESTful API architecture with JSON responses
- PostgreSQL Database: Relational database design for student and workshop management
- Scalable Architecture: Backend designed to handle concurrent user registrations
- Data Integrity: Robust validation and error handling for reliable data management
