n8n production automations
Haris Umer
At CoalDev I built n8n agent workflows that stayed up. A business trigger starts the run, an LLM step classifies or drafts, embeddings go into Postgres with PGVector, and a failed run hits an error branch instead of disappearing. This is the automation I still take on as a one-week sprint.
