c++ programmer -- 2

I am in need of an experienced C++ programmer to assist with optimizing my code for better performance. I would prefer an expert level freelancer who is comfortable working with both existing code bases and starting from scratch. This task requires someone with excellence in coding, analyzing, troubleshooting, and debugging complex code structures. A strong familiarity with modern C++ development practices is also desired. Ideally, the freelancer will have proven results working with similar projects and can provide information on their experience. I look forward to receiving bids from experienced developers who successfully meet these criteria.
