Knowledge that goes deeper
Master your own business automation
Hi, I'm Mario. I teach tech-savvy professionals how to build automation – with n8n – that they can maintain, extend, and own without depending on anyone else.
Most automation projects don't fail because of technology
They fail because the foundation is missing:
- Teams invest in tools without understanding their own workflows
- They automate broken processes
- They depend on external agencies for every change
- When something breaks, nobody knows why
The result: fragile automations, growing dependency, and wasted potential.
I start where others skip ahead
Before a single workflow gets built, I help you answer the real questions:
I analyze the root cause, not the symptom. Then I guide you through building automation that you truly understand – with your real business cases, not textbook examples. The goal is never dependency. The goal is self-reliance.
Three ways to work with me
Hands-on Workshops
For teams exploring whether n8n is right for their business.
Interactive group sessions for 2-4 participants where everyone gets hands-on. I prepare a real use case tailored to your business and guide your team through building it together – pair-programming style.
1:1 Mentoring
For founders and team members who want to build with depth.
A deep, ongoing partnership where I guide you through mastering n8n automation at your own pace. We work with your real use cases, not tutorials. Includes chat support between sessions so you never get stuck or blocked.
Consulting & Assessment
For experienced n8n users who need expert guidance.
Architecture advisory, best practices review, and live solution assessments. I look at what you've built and give you direct, actionable feedback on security, scalability, and structure.
Every engagement starts with a free consultation – no commitment, no pressure. Let's find out if we're a good fit.

I'm Mario Haarmann, a Certified n8n Expert Partner and Certified Software Architect. Automating manual processes has been my thing since day one. It's what got me into software development in the first place, and it's what I still do today – only now with n8n, which makes it dramatically faster.
I don't run an agency. Instead, I work personally with every client. That means fewer clients, more depth, and better results. I only take on work where I can genuinely make a difference, and I say no to projects that don't align with my values.
My approach combines technical precision with a genuine interest in how people learn and grow. I don't just teach you the "how" – I make sure you understand the "why." Because that's what makes the difference between automation that breaks and automation that lasts.
