Hi @Filasophia,
I build production n8n workflows. Not sandbox experiments, not demos for clients to validate and never deploy. I come from a manufacturing background so I think about automation from an operational standpoint: it has to run reliably, it has to be maintainable by whoever comes after me, and it has to be secure.
On your specific use cases:
Order processing into Excel without manual input is a straightforward but unforgiving flow. I have built similar pipelines that capture inbound data, validate it, and write to structured sheets with error handling so bad records don’t silently corrupt your output.
Google Drive folder creation and PDF routing I have running in production. The logic around conditional routing and folder hierarchy is something I handle cleanly.
Email classification and routing by department is an AI classification workflow I have built before, using n8n with an LLM step to categorize and then route accordingly.
Lead collection from scheduled social/web sources I have done with both API integrations and scraping-adjacent approaches depending on what the source allows.
On security: API key management through n8n’s credential system, environment variables for secrets, no plaintext credentials in workflow nodes, and access controls configured at the instance level. That is baseline for me, not an afterthought.
I prefer long-term engagements over one-offs too. Consistent work with one client beats juggling five.
One question before I DM you a portfolio: are most of these workflows on your existing self-hosted n8n instance, or are you still deciding on infrastructure?
