challenge
Sail Croatia is a travel service with more than 13,000 visitors per month, so employees could not process all the orders manually. That's why it was decided to create a CRM system where most processes can be automated.
The main problem during development was lots of unmaintainable legacy code that was received from the previous vendor. So, we decided to use patterns to isolate and break down old code into small pieces and refactor it to acceptable, clean code.
full-cycle travel CRM development
We developed a custom system tailored for travel and tour operators managing yacht charters, cruises, and excursions. The platform supports the entire customer lifecycle: from lead capture and booking management to payments, documentation, and post-trip communication.
The system centralizes booking data, availability tracking, and operational workflows. Managers can efficiently handle reservations, allocate yachts and services, track trip details, and manage customer records within a single environment.
Background job processing with Sidekiq and Redis ensures smooth handling of time-sensitive tasks such as confirmations and updates.
Utilizing Golang for microservices in CRM development enabled a robust payment transaction flow. Furthermore, we employed Go to create an online check-in system, significantly enhancing the performance of this feature.
automated communication system
We implemented automated transactional and marketing communication flows using SendGrid. The CRM triggers booking confirmations, payment reminders, travel documents, and follow-ups, ensuring consistent and timely customer communication.
advanced search & data management
Using PostgreSQL and Solr, we optimized search and filtering across bookings, customers, and trips. This allows managers to quickly access critical information, even during high-load seasonal periods.
cloud infrastructure upgrade & database migration
We migrated the database to AWS RDS, separating it from the main application server and moving it to a managed cloud environment. This ensures that all critical data is stored on a dedicated, stable instance independent from application-level failures.
The migration introduced automated backups and storage auto-scaling, eliminating the need for constant manual monitoring of disk space and backup integrity. It also reduced system load, particularly during heavy operations such as large report generation.
As a result, the infrastructure became more resilient, easier to maintain, and significantly more reliable, giving the client confidence that their data is secure, backed up, and consistently available.
4 cross-platform mobile apps for tourists
Building on our CRM partnership, we developed a mobile ecosystem for Sail Croatia and MedExperience.
Choosing React Native allowed us to launch 4 iOS and Android apps from a single codebase, nearly doubling development efficiency (1.9x faster than native development).
We automated the guest journey by syncing booking data with the CRM in real-time, while offline maps ensure seamless navigation even at sea without a network connection.
