Challenge

Before

A legacy benefits platform at the scale of millions was blocking the next phase of growth — slow search, no multilingual support, and rising operational effort.

Slow DB search — employees can't find the benefits they want
5s+ search lag / drop-off
Multilingual support for foreign employees is hard
No English / Chinese / Vietnamese support
Operational load of the legacy platform
Consumes 60% of SRE team effort
Migrate to the new platform without stopping millions of users
Tens of millions of PV per month

Solution

After

Vue 3 + TypeScript front end, a Spring Boot BFF, AWS Lambda + OpenSearch to isolate search, and Terraform IaC for reproducibility. Wovn multilingual, with parallel old/new operation delivering a zero-downtime overhaul.

Benefits search — 0.08s response with OpenSearch; multilingual support lets foreign employees use it too.
