🏗️ Architecture

The application follows Object-Oriented Programming (OOP) principles with a clean, layered architecture:

Service Layer

• ResumeService: Encapsulates resume operations (upload, parse, analyze, generate)
• SessionService: Manages user session state and data persistence

Controller Layer

• ResumeController: Handles HTTP requests and coordinates services

Application Layer

• JobResumeChangerApp: Main application orchestrator
• ApplicationConfig: Centralized configuration management

OOP Patterns Used:

• Service Layer Pattern
• Dependency Injection
• Controller Pattern
• Factory Pattern (create_app)
• Composition over Inheritance

See OOP_ARCHITECTURE.md for detailed architecture documentation.

🔒 Security Notes

Important: This application is designed for development and personal use. Do not deploy to production without proper security measures.

• The application stores files temporarily during processing
• Uploaded files are stored with unique session IDs
• Files are stored locally on the server (not recommended for production without additional security)
• Debug mode is disabled in production when FLASK_ENV=production is set

For Production Deployment:

Required:

1. Set environment variable: FLASK_ENV=production
2. Set a secure secret key: SECRET_KEY=<your-secure-random-key>
3. Use a production WSGI server (e.g., Gunicorn, uWSGI) instead of Flask's built-in server
4. Enable HTTPS/SSL certificates

Recommended:

• Add user authentication and authorization
• Use cloud storage with encryption for file uploads
• Implement automatic file cleanup routines
• Add rate limiting to prevent abuse
• Set up logging and monitoring
• Use a reverse proxy (nginx, Apache)
• Implement CSRF protection
• Add input validation and sanitization
• Set up a firewall and security groups

Example Production Setup:

# Set environment variables
export FLASK_ENV=production
export SECRET_KEY=$(python -c "import secrets; print(secrets.token_hex(32))")

# Run with Gunicorn
pip install gunicorn
gunicorn -w 4 -b 0.0.0.0:8000 app:app

🐛 Troubleshooting

"Error processing upload"

• Ensure your resume file is in PDF, DOCX, or TXT format
• Check that the file size is under 16MB
• Try converting your resume to a different format

"No missing points found"

• Your resume may already be well-aligned with the job description
• Try with a more detailed job description
• Ensure the job description contains specific requirements

Resume generation fails

• Check that you've added at least one point
• Ensure you have write permissions in the application directory
• Try generating in TXT format first

🌐 Browser Compatibility

• Chrome (recommended)
• Firefox
• Safari
