From Bottlenecks to Self-Service: Workflow-as-a-Service with Temporal Nexus

on YouTube ↗44m

" summary

Duolingo turns Temporal Nexus into a company-wide workflow-as-a-service platform: a gateway microservice + JSON-schema portal lets engineers trigger validated, auditable cross-namespace workflows while CloudOps retains approval control via signals and Slack notifications. Implementation uses a router worker per namespace, Nexus operations for shared concerns (Slack, CI), and durable AI-driven assistants and CLI. Outcome: ~50 registered workflows, onboarding cut from hours to under five minutes, large reductions in copy‑paste toil, and the system runs in production with measurable time savings.
