Python Developer Needed for Trading Algorithm Backtesting

I'm looking for an experienced Python developer to help me implement backtesting functionality for my trading algorithm.

**Project Overview:**
My algorithm currently works as follows:
1. Collects financial indicator data
2. Sends this data to a REST web service
3. Receives trading predictions from the web service
4. Makes trading decisions based on these predictions

**What I Need:**
- Implementation of backtesting framework in Python
- Historical data integration and processing
- Performance metrics calculation (returns, Sharpe ratio, drawdown, etc.)
- Code optimization and testing
- Documentation of the backtesting system


**Deliverables:**
- Clean, well-documented Python code
- Backtesting results with performance analysis
- Clear instructions for running and modifying the system

Please include in your proposal:
- Examples of similar backtesting projects you've completed
- Your approach to implementing this system
- Estimated timeline for delivery

Looking forward to working with a skilled developer on this project!
