Desktop Quote & Invoice Software Development

I'm seeking an expert to develop a desktop application for quote generation, invoicing, and export documentation, tailored for Indian exporters.

I've started building this with AI-generated Python code but need help to:
- Review and fix existing codebase
- Build or improve all key modules: quote, invoice, export docs
- Ensure smooth functionality and robust error handling
- Complete and deploy the software

Ideal Skills and Experience:
- Expertise in desktop app development
- Proficiency in Python
- Experience with invoicing systems and export documentation tools
- Strong problem-solving skills and attention to detail

I look forward to collaborating with someone who can bring this project to fruition.
