The Workflow Engineer

About this workbook

A 26-chapter field manual for building workflow automation that survives contact with production — n8n-centric but stack-agnostic. Covers the Code node, webhooks at scale, data transformation, LLMs in production workflows, error handling, self-hosting, and the architecture patterns that keep automation from becoming the glue code nobody owns.
