KEY TECHNICAL PROJECTS

Enterprise Inventory RAG Assistant (XML to Vector DB)

●​ The Challenge: An e-commerce business needed to answer stock queries instantly, but
data was locked in a dynamic XML file and separated from the CRM.
●​ The Solution: Built a complex n8n workflow that parses XML feeds, syncs data to
Supabase, and updates a Vector Database in real-time.
●​ Tech Logic: Implemented a RAG architecture where the AI Agent queries the database
before answering. Used JavaScript within n8n to format data for the LLM.
●​ Impact: Enabled a fully automated "Check Availability" feature for Instagram, removing
the need for managers to manually check Excel files.
"Human-in-the-Loop" Lead Gen System

●​ Architecture: Designed a fail-safe automation where AI qualifies leads up to a specific
point.
●​ Logic: If the AI confidence score is low or the lead asks a complex question, the system
automatically pauses the bot and triggers a Telegram Alert to a human manager with
the full chat context.
●​ Result: Balanced automation speed with human quality control, preventing AI
hallucinations in critical sales conversations.

Intelligent Email System (Gmail + GPT-4o)

●​ Workflow: Automated inbox management using n8n Gmail nodes. The system reads
incoming emails, uses GPT-4o-mini to categorize them by urgency/sentiment, and
pushes "High Priority" alerts to Telegram/Slack.
