AI Workflow System: Production-Ready Automation Architecture

Treat AI workflows like real systems, not demos

A production-grade framework for building reliable AI automation systems using modular architecture patterns. This repository demonstrates how to architect sophisticated AI workflows with clear separation between orchestration, retrieval, reasoning, and side effects.

🎯 Philosophy

AI workflows should be treated as distributed systems with:

• Clear separation of concerns: Orchestration, retrieval, reasoning, and side effects
• Production-ready patterns: Error handling, state management, observability
• Modular design: Swap components without breaking the system
• Real-world reliability: Not just demos—actual production deployments

Component Breakdown

Component	Responsibility	Examples
Orchestration	Workflow coordination, state management	n8n, Temporal, Prefect
Retrieval	Knowledge gathering, context building	RAG, vector stores, embeddings
Reasoning	Decision making, content generation	LLM agents, tool calling
Side Effects	External interactions	API calls, database writes, notifications

🚀 Quick Start

Option 1: Docker (Recommended)

# Clone the repository
git clone https://github.com/yourusername/AI-Workflow-System.git
cd AI-Workflow-System

# Copy environment template
cp docker/.env.example docker/.env

# Edit .env with your API keys
nano docker/.env

# Launch the stack
cd docker
docker-compose up -d

# Access n8n at http://localhost:5678

Option 2: Manual Setup

# Install n8n globally
npm install -g n8n

# Start n8n
n8n start

# Import workflows from examples/
# Navigate to http://localhost:5678
# Settings → Import from File → Select AI content engine RAG + n8n.json

📚 Use Cases

Use Case	Description	Example Workflow
LinkedIn Content Automation	Ingests GitHub repos, builds RAG knowledge base, generates technical posts	examples/linkedin-automation/
Code Review Automation	Analyzes PRs, extracts insights, posts review comments	examples/code-review-automation/
Knowledge Base Sync	Maintains internal documentation from multiple sources	examples/internal-tooling/knowledge-base-automation/

💡 Example Output

Here's a LinkedIn post generated by the LinkedIn automation workflow:

"Just reviewed a clean architecture implementation that uses mediator pattern for domain events. The abstraction ensures business logic remains pure while infrastructure concerns are handled separately. Key takeaway: strategic separation of concerns isn't just theoretical—it directly reduces bug density in complex systems.
