Enterprise Travel Platform Architecture

Re-architected a legacy monolith into a domain-driven microservices platform powering enterprise travel workflows.

About this project

A legacy travel platform had reached its scaling and feature-velocity ceiling; integrations with airline/GDS/hotel APIs were tightly coupled and brittle.

Solution

Strangler-pattern migration to bounded-context services, async event backbone, and a unified GraphQL gateway. Phased over 18 months with zero production outages.

Technology

  • Java
  • MongoDB
  • MariaDB
  • RabbitMQ
  • GraphQL
  • Kubernetes

Impact

Feature lead time fell from 6 weeks to 8 days; platform absorbed 4× peak booking traffic with no degradation.
