• Build automated testing infrastructure for agent pipelines, including unit, integration, replay-based, and regression testing.
• Define and monitor reliability metrics such as task completion rate, escalation rate, workflow success rate, cost per workflow, latency, and SLA adherence.
• Build systems that enable rapid debugging and root-cause analysis of complex agent workflows.

Reliability, Security, and Compliance:

• Design enterprise-grade systems with strong monitoring, alerting, fault tolerance, and disaster recovery.
