I'm seeking an experienced Python programmer to help me create a WebSocket project for real-time financial data streaming. This project involves not just raw data transmission, but also significant preprocessing and transformation of the data before it is sent through the WebSocket.

Ideal skills and experience for the job:
- Proficiency in Python and WebSocket technology
- Experience with real-time data streaming
- Background in financial data handling
- Capable of implementing data preprocessing and transformation techniques

Please only apply if you have the relevant skills and experience, and a proven track record in similar projects.
