Virgin Voyages Crew App
Enterprise-scale React Native application for crew management, operations, and shipwide communication
Overview
As the lead mobile engineer, I architected and built a mission-critical React Native application used by thousands of crew members across Virgin Voyages' fleet. The app handles scheduling, task management, real-time notifications, and shipwide communications.
The Challenge
Virgin Voyages needed a reliable, high-performance mobile solution that could operate in environments with limited connectivity while handling real-time updates for thousands of crew members. The app needed to integrate with multiple backend services, including Java microservices, Kafka message streams, and WebSocket connections for live updates.
The Solution
Architecture
Built a robust React Native architecture with offline-first capabilities, optimistic updates, and intelligent caching. Implemented Redux for state management and Redux-Saga for handling complex async workflows.
Real-time Communication
Integrated WebSocket connections for live messaging and notifications. Connected to Kafka streams for event-driven updates across the fleet. Implemented smart reconnection logic and message queuing for unreliable network conditions.
Performance Optimization
Reduced app launch time by 40% through code splitting and lazy loading. Optimized list rendering with React Native's FlatList and implemented advanced memoization patterns. Added comprehensive monitoring with Sentry and custom analytics.
