[n8n] Simplify automation setup for non-coders

I’m currently learning automation tools like Make and n8n, along with other no-code tools. My concern is about the long-term sustainability of systems built this way. It’s easy to create automations quickly, but I’m wondering if they can become messy or hard to maintain over time, especially when workflows grow or multiple automations depend on each other. For those of you who build automation systems professionally: * What practices do you recommend from the beginning to keep things clean and scalable? * How do you structure workflows so they don’t become a “spaghetti system” later? * Do you document flows, modularize them, or use naming conventions? * At what point do you move from no-code to custom code? I’m trying to learn the right habits early so I don’t build systems that become fragile later. Any advice or lessons learned would be really helpful.
