# Jan Repnak

> Solutions Architect at n8n, based in Lüneburg, Germany. I help teams design workflow automation that holds up in production.

## Profile

I specialize in automation. At [n8n](https://n8n.io/), I help customers design production workflow automation and move AI agents from demos into systems teams can operate, monitor, and trust.

Before n8n, I helped enterprises design secrets management with HashiCorp Vault. That experience shapes how I approach AI agents: an agent is an identity with credentials and should never have more access than its current task requires.

## Focus areas

- **n8n enterprise architecture:** Reference architectures on AWS and Kubernetes, queue mode at scale, custom nodes, and large deployment patterns.
- **Workflow design and error handling:** Idempotent steps, retries, dead-letter paths, and production observability.
- **AI agents in production:** Evaluations, human-in-the-loop controls, and telemetry.
- **Agent identity and access:** Least privilege, scoped credentials, secrets management, and audit trails.

## Technology

n8n, AI agents, Model Context Protocol (MCP), OpenTelemetry, HashiCorp Vault, OAuth 2.0, OpenID Connect, Terraform, Proxmox, Talos Linux, Kubernetes, Podman, JavaScript, Go, and Bash.
