From Bottlenecks to Self-Service: How Duolingo Built Workflow-as-a-Service with Temporal Nexus
ABSTRACT
We built a self-service platform on Temporal Nexus, enabling cross-namespace, secure workflows with human-in-the-loop controls. This transformation boosted developer productivity, eliminated manual toil, and spurred adoption. Today it’s expanding into a company-wide platform: teams expose their own workflows via Nexus, and we’re scaling Slack integration, onboarding, and governance.
