+**Complexity**: Level 3 → Simplified to Level 1 → Enhanced to Enterprise Grade  
+**GitHub PR**: #93 (6 commits, comprehensive code review)
+
+## Problem Statement
+n8n workflows were stored only in PostgreSQL database without version control, creating risks of data loss and making it difficult to track changes, deploy to different environments, and collaborate on workflow development.
+
+## Solution Implemented
+Created a minimal, enterprise-grade automated backup system that exports n8n workflows to a Git repository with the following features:
+
+### Core Components
+1. **Workflow Export Script** (`scripts/n8n-backup.sh`)
+   - POSIX-compatible automation with strict mode
+   - Automated n8n CLI workflow export
+   - Modern Git practices (main branch, local config)
+   - Comprehensive staging and push logic
+   - Dynamic branch detection and upstream tracking
+
+2. **Docker Integration**
+   - Secure package installation with version pinning
+   - Volume mapping for script access
+   - Persistent storage in n8n_data volume
+   - Hadolint-compliant Dockerfile
+
+3. **Code Review Integration**
+   - CodeRabbit AI filtering configuration
+   - GitHub Actions compatibility
+   - Security best practices compliance
+
+4. **Directory Structure**
+   ```
+   /home/node/.n8n/workflows/
+   ├── .git/              # Git repository
+   ├── README.md          # Documentation
+   └── (exported workflows in JSON format)
+   ```

+- **Temporal.io**: Workflow orchestration engine
+  - Version: 1.11.8 (Workers, Client, Activities, Workflow)
+  - Features: Durable execution, automatic retries, visibility
+  - Worker Implementation: Custom TypeScript workers in `workers/main/`
+
+### Automation Interface
+- **n8n**: Visual workflow automation platform
+  - Containerized deployment
+  - PostgreSQL backend for workflow storage
+  - Redis for session management and caching
+
+### Data Persistence
+- **PostgreSQL**: Primary database for n8n and Temporal
+- **MongoDB**: Document storage (via Mongoose 8.15.1)
+- **MySQL**: Secondary relational data (via mysql2 3.14.1)
+- **Redis**: Caching and session storage
+
+### Infrastructure
+- **Docker**: Containerized deployment with custom images
+- **Docker Compose**: Multi-service orchestration
+- **Custom Dockerfiles**:
+  - `Dockerfile.n8n`: Extended n8n image
+  - `Dockerfile.temporal`: Extended Temporal auto-setup
+  - `Dockerfile.temporal-worker-main`: Main worker container
+
+## Development Toolchain
+
+### Code Quality
+- **ESLint**: Strict linting with TypeScript support
+- **Prettier**: Code formatting (version 3.5.3)
+- **TypeScript**: Strict type checking (version 5.8.3)
+
+### Testing Framework
+- **Vitest**: Fast unit testing (version 3.1.3)
+- **Coverage**: C8 and @vitest/coverage-v8 for test coverage
+- **Temporal Testing**: @temporalio/testing for workflow testing
+
+### HTTP Client
+- **Axios**: HTTP requests with rate limiting and retry logic
+  - `axios-rate-limit`: API rate limiting
+  - `axios-retry`: Automatic retry mechanisms
+
+## Key Integrations
+
+### External Services
+- **Slack API**: Automated notifications (@slack/web-api 7.9.2)
+- **OAuth2**: Token management (simple-oauth2 5.1.0)
+- **QuickBooks**: Financial data integration (via OAuth2)
+
+### Data Validation
+- **Zod**: Runtime type validation and schema parsing (3.25.17)
+- **Schema-driven**: All external data validated through Zod schemas
+
+## Architecture Patterns
+
+### Worker Architecture
+```
+workers/main/src/
+├── activities/          # Temporal activities (business logic)
+├── workflows/          # Temporal workflows (orchestration)
+├── services/           # Business service layer
+├── configs/            # Configuration management
+└── common/             # Shared utilities and types
+```
+
+### Service Layer Design
+- **Repository Pattern**: Data access abstraction
+- **Error Handling**: Custom error types for different domains
+- **Type Safety**: Comprehensive TypeScript types
+- **Testing**: Unit tests for all service components
+
+### Configuration Management
+- **Environment Variables**: Docker-based configuration
+- **Type-safe Config**: Validated configuration objects
+- **Multi-environment**: Development, production, and testing configs
+
+## Security Considerations
+- **OAuth2 Flows**: Secure token management
+- **Environment Isolation**: Containerized services
+- **Database Security**: Connection pooling and credentials management
+- **API Rate Limiting**: Protection against abuse
+
+## Performance Optimization
+- **Connection Pooling**: MongoDB and database connections
+- **Rate Limiting**: Controlled API usage
+- **Retry Strategies**: Intelligent failure handling
+- **Memory Management**: Efficient worker resource usage
+
+## Monitoring and Observability
+- **Temporal UI**: Workflow execution monitoring
+- **Logging**: Structured logging with configurable levels
+- **Health Checks**: Service health endpoints
+- **Metrics**: Performance and usage metrics collection
+
