B2B Automotive Web App Development

I'm looking for an experienced developer to create a private, login-based B2B web application for verified car dealers and trusted reference users. The platform will provide access to various automotive-related services through third-party APIs, all wrapped within a credit-based wallet system. Additionally, it will serve as an internal playground for showcasing valuable APIs to a closed user group.

Key Requirements:
- User roles: Car dealers, trusted reference users, and API administrators
- Integration of various automotive-related services via third-party APIs (detailed API documents and keys will be provided)
- Implementation of a credit-based wallet system

Ideal Skills and Experience:
- Strong background in web application development
- Experience with API integration
- Familiarity with credit/wallet systems
- Prior experience in building B2B platforms
- Strong security measures for login-based applications

Please provide a portfolio showcasing similar past work and relevant experience.
