Built an AI-powered lead qualification workflow using n8n and an LLM. The automation receives lead data through a webhook, extracts structured information, evaluates intent and lead quality, validates the output, classifies leads as HOT/WARM/COLD, and routes the result for downstream processing. Designed with structured outputs and deterministic validation to keep business decisions reliable.

Lost 2 days building a complex n8n workflow. Here's what I learned.✌️
The project: A 12-node AI Receptionist automation for a luxury resort in Bangladesh. Multi-channel (WhatsApp, Telegram, Voice), 9 Google Sheets, Gemini API, payment automation, customer CRM.
What went wrong: Added a new voice integration node. Accidentally deleted the entire workflow.
Why it happened:
No JSON exports after milestones
No version control (Git)
Testing changes LIVE on production workflow
No documentation
Building locally with zero redundancy
The fix (now implemented):
✅ JSON backups after every 2-3 nodes
✅ GitHub versioning
✅ Clone workflows for testing
✅ Modular design
✅ Complete documentation
For automation professionals: You're not just builders—you're engineers.
Treat workflows like software:
Documentation
Version control
Backup strategy
Modular testing
Client delays = lost revenue + credibility damage.
Make the systems bulletproof.

I'd try restoring one of those JSON backups into a cloned workflow before the next handoff. That way you know it can actually get you running again.

Self-built AI automation demo using n8n and LLMs to handle common e-commerce support requests. The workflow combines external REST API lookups, RAG-based policy retrieval, session memory, structured validation, retry handling, execution logging, and failure alerts. Built with a production-oriented approach where AI handles language understanding while deterministic workflow logic handles validation and system actions.
