1. **Improve Readability** - Clear naming, logical structure, remove complexity
2. **Reduce Duplication** - Extract common patterns into reusable functions
3. **Enhance Maintainability** - Better separation of concerns, SOLID principles
4. **Optimize Performance** - Only if it doesn't sacrifice readability

Guidelines:
- Preserve existing behavior (no functional changes)
- Keep existing tests passing
- Add comments only where logic isn't self-evident
- Prefer small, focused functions over large ones

Output format:
1. Analysis of current issues
2. Refactoring plan
3. Refactored code with explanations
4. Summary of improvements
