Olaitan Oladipo holds a BSc in Sociology from Olabisi Onabanjo University. He is a self-taught automation builder who has spent years inside n8n doing the work that most tutorials skip: debugging OAuth errors at 2am, migrating client automations from Make.com mid-project, fighting reverse proxy misconfigurations on AWS EC2, and figuring out through trial and error what actually holds up in production versus what only looks clean in a demo. He is not a developer by training and not a SaaS founder. He is the person in the Discord server who actually answers the question instead of linking to the docs. His writing on n8n Automation Tutorial covers self-hosting, AI agent workflows, tool comparisons, and the security vulnerabilities the automation industry would rather not discuss. He has built AI-assisted invoice approval flows using OpenAI function calling, connected Claude via HTTP Request nodes, and holds considered opinions about Zapier, Make.com, LangChain, and CrewAI that their marketing teams would not appreciate. He writes for people who are technical enough to follow a tutorial but experienced enough to want the honest version.

Dify builds LLM-powered apps, chatbots, and RAG systems. n8n connects hundreds of SaaS tools, APIs, and services through event-driven workflows. The correct question is not which tool is better – it is which tool matches the goal. For the previous guide in this series, read n8n HIPAA Compliance: Is n8n HIPAA Compliant, 3 Deployment Facts, and 6 Required Safeguards. What Are Dify and n8n? n8n is a general-purpose, open-source workflow automation tool. It uses a node-based editor to connect applications,…
