PerkConcierge is an employee benefits platform used across tens of thousands of corporate contracts and millions of users. Its new Vue 3 + Spring Boot + OpenSearch foundation improves search performance, multilingual UX, and operational efficiency end to end.
We rebuilt the legacy platform — once defined by "slow DB search, no multilingual support, 60% of SRE effort consumed, and legacy maintenance at its limit" — together with Enterprise Benefits Service Operator, reaching a next-generation foundation through 18 months of zero-downtime modernization. A business transformation story.
A leading domestic employee-benefits provider with tens of thousands of corporate contracts and a user base in the millions. Across many categories — hot springs, dining, sports, childcare support and more — it is an infrastructure-grade service underpinning corporate HR strategy.
After more than a decade in operation, the legacy platform had hit its limits — slow search, no multilingual support, and heavy operational load. Migrating to a next-generation platform without halting the business was the key to continuity.
We treated this not as a technical issue but as a management challenge tied directly to usage rates, contract retention, operational efficiency, and business continuity — and modernized on that basis.
Vue 3 + TypeScript front end, a Spring Boot BFF to organize business logic, AWS Lambda + OpenSearch to isolate search, and Terraform IaC for reproducible environments. Wovn for multilingual support, with parallel old/new operation enabling a zero-downtime cutover.
