Travel Booking Platform
Complete booking system with web, iOS, and Android apps
The founders needed a travel marketplace that handled complex availability logic, multi-currency payments, and booking management across three platforms — web, iOS, and Android.
The Challenge
The founders needed a travel marketplace that handled complex availability logic, multi-currency payments, and booking management across three platforms — web, iOS, and Android. Previous attempts with offshore teams had stalled due to the complexity of real-time inventory sync and payment processing across timezones.
Our Solution
We built the backend with Django REST Framework and Celery task queues for handling asynchronous booking confirmations, payment processing, and availability updates. The web frontend was built with React, while React Native powered cross-platform mobile apps sharing 85% of their codebase. The admin dashboard gives operators full control over listings, bookings, and revenue reporting. Everything is containerized with Docker and running on AWS with auto-scaling.
The Results
Launched across Web, iOS, and Android simultaneously within 12 weeks
Processes bookings in 5+ currencies with Stripe Connect for split payments
Handles 10K+ concurrent availability checks with sub-200ms response times
Technical Approach
Django REST Framework was chosen for its mature serialization and permission system, critical for multi-role access (travelers, hosts, admins). Celery with Redis handles booking confirmation flows that involve external API calls to partners. React Native was the clear choice for mobile — the client needed both platforms but had budget for one codebase. AWS ECS handles container orchestration with RDS for PostgreSQL.
“Our previous development team left us with a half-finished product and a pile of technical debt. Evolvera took over, cleaned up the codebase, and shipped the remaining features in 6 weeks. They saved our launch.”
