Accounting Firm Web & Mobile App Development

I'm looking for a talented developer to create a comprehensive web application for my accounting firm in South Africa, with the long-term vision of extending it to other firms. The web app should be seamlessly convertible into a mobile application for both iOS and Android platforms.

Key Requirements:
- **Client Management:** The app should have robust client management capabilities.
- **CSV Transformation:** It should have the ability to transform CSV files into a specified layout that can be saved or printed as PDF.
- **Mapping Code:** Each category should have a different mapping code which can be applied to the PDF.

Please note:
- The mobile app should mirror the functionality of the web app.

Ideal Skills:
- Proficiency in web development
- Experience in mobile app development (iOS and Android)
- Knowledge in data transformation and PDF generation
- Understand the nuances of accounting software

If you have a good understanding of accounting processes and are able to create a seamless user experience for both web and mobile platforms, I'd love to hear from you.
