## Overview

This repository is a portfolio of eight n8n automation workflows, not a shared application runtime. The graph summarizes each workflow’s documented user-to-result stages and integrations. Only the root README and file tree were provided; relationships and capabilities are based on their descriptions, not inspection of the workflow JSON files.

Main entry points: [`AI-Powered Customer Support Email Automation/Customer Support Workflow.json`](https://github.com/mostafa7arafa/n8n-workflow-portfolio/blob/main/AI-Powered%20Customer%20Support%20Email%20Automation/Customer%20Support%20Workflow.json) (Email support bot), [`Telegram AI Chatbot with Human-in-the-Loop (HITL) Approval/Human in loop.json`](https://github.com/mostafa7arafa/n8n-workflow-portfolio/blob/main/Telegram%20AI%20Chatbot%20with%20Human-in-the-Loop%20(HITL)%20Approval/Human%20in%20loop.json) (Telegram HITL bot), [`Automated LinkedIn Post and Image Generation Pipeline/Automated LinkedIn Post and Image Generation Pipeline.json`](https://github.com/mostafa7arafa/n8n-workflow-portfolio/blob/main/Automated%20LinkedIn%20Post%20and%20Image%20Generation%20Pipeline/Automated%20LinkedIn%20Post%20and%20Image%20Generation%20Pipeline.json) (LinkedIn post generator), [`automated-pdf-invoice-processing/Invoice reader (pdf).json`](https://github.com/mostafa7arafa/n8n-workflow-portfolio/blob/main/automated-pdf-invoice-processing/Invoice%20reader%20(pdf).json) (PDF invoice processor)
