### Abstract

At Airwallex, a global financial platform in 150 countries, our legacy microservice architecture caused constant alerts and sleepless nights.

This case study shows how we fixed issues in our third-party adapter microservices, originally designed with choreography, without a risky full rebuild. By using Temporal to wrap our legacy code, we stabilized the system, reduced incidents, and boosted developer productivity by 6x—all while continuing to deliver new features.

Watch the talk to learn practical steps for modernizing microservices without disrupting your roadmap!
