Advanced Crypto-Powered Proxy Dashboard Development

I am in need of a specialist to build a versatile and dynamic dashboard for my business. The tool should be capable of satisfying the following requirements:

- Proxy Provisioning: The dashboard should facilitate my clients in making requests for new proxies. Additionally, it has to be capable of auto provisioning proxies based on given client specifications. Tracking, managing and reporting of proxy usage are also vital features that I am looking for.

- API Call Management: Streamlining application interactivity is key. The solution should allow efficient management of different API calls.

- Cryptocurrency Payment Integration: Given the rise in the popularity of digital currencies, I need the system to handle payment transactions in Bitcoin and Tether (USDT).

- User Management: To ensure seamless operations, capabilities around sound user management are necessary.

- Data Analytics: The platform should facilitate the analysis of key business metrics and data.

Ideal candidates for this project will have excellent technical proficiency in the areas of back-end development, API integration, data management, cryptocurrency systems and user interface design. Familiarity with the latest trends and best practices in proxy service provision will also be a significant advantage.
