B2B OTA Platform – Moonholidays

Overview

Moonholidays is a full-featured B2B OTA (Online Travel Agency) platform built to streamline the wholesale travel booking process for agents and corporate accounts across Southeast Asia.

The platform handles hotel, flight, and package bookings with real-time availability checks powered by Elasticsearch for sub-100ms search responses across millions of inventory records. Redis caching ensures frequently-requested routes and room availability are served instantly without hitting the database on every request.

A Node.js microservices backend manages booking flows, payment processing, and commission calculations, while a React front-end provides travel agents with an intuitive dashboard to manage client bookings, view reports, and configure mark-up rules. PostgreSQL stores transactional data with full ACID compliance, and background workers handle booking confirmations, voucher generation, and email notifications asynchronously.

Key achievements include reducing search latency by 85% after introducing Elasticsearch, and scaling the platform to support over 500 concurrent travel agent sessions.
