Logistics Platform — Naval Travel & Transportation Industry
Case Study
Designed and delivered the migration of a legacy system to event-driven microservices using
Spring Boot 3. The platform handles the complete lifecycle of naval logistics — scheduling voyages,
managing passenger and freight manifests, processing bookings and payments — all while operating
in lock-step with the existing AS400/DB2 backend during the client's gradual adoption phase. The
result: a fully modernised core with zero service disruption and full data consistency throughout
the transition.
