C++ FIX Client for Binance & Kraken

I'm looking for an experienced C++ developer to create a FIX client that can interface with the FIX APIs provided by Binance and Kraken. This project requires a deep understanding of low-latency coding practices, as the implementation needs to be optimized for performance.

Key Requirements:
- Experience with C++ and low-latency coding practices
- Prior work with FIX protocol
- Familiarity with Linux (Ubuntu) environment
- Understanding of financial trading APIs, specifically Binance and Kraken

The FIX client you develop must prioritize low-latency performance. Robust error handling and scalability, while important, are secondary to achieving optimal speed.

The client must be delivered with detailed comments and a comprehensive README. This will ensure that the code is understandable and accessible for future enhancements or troubleshooting.

Skills Required:
- C++
- Low-latency coding
- FIX protocol
- Linux (Ubuntu)
- Trading APIs (Binance, Kraken)
- Software Documentation
