8+ Hours Per Day, 3+ Weeks Straight — Orchestrating a 3-Actor Email Production Pipeline

The Pipeline

The email production pipeline involves three actors working in sequence: DBOS (a durable execution framework) handles workflow orchestration and failure recovery; PostgreSQL manages state and job queues; S3 handles email content storage; Gmail API handles delivery. Hermes coordinates all three, managing handoffs, retrying failures, and maintaining pipeline state.

• DBOS: durable workflow orchestration with automatic failure recovery
• PostgreSQL: state management and job queue persistence
• S3: email content and attachment storage
• Gmail API: final delivery and read-receipt tracking

Production Intensity

Running at 8+ hours per day for three weeks is a different regime from most AI agent deployments. Most demos run for minutes. Most tutorials run for hours. Production pipelines run indefinitely. The fact that Hermes maintained consistent operation across this period — without session degradation, memory overflow, or error accumulation — is the most concrete proof of production readiness available.

What This Means for Enterprise Adoption

This use case establishes a template for enterprise-grade Hermes deployment: a single persistent instance orchestrating multiple infrastructure components, running at production intensity, with Claude Opus via OpenRouter providing the reasoning layer. The architecture is replicable for any complex, multi-system workflow that currently requires human coordination.
