I will optimize and refactor your cpp code for better performance


About this gig
Slow C++ code? I make it faster. I have 14+ years of professional C++ experience building performance-critical software automotive systems, navigation engines and real-time market data, where speed and efficiency are not optional.
What I can do:
- Profile your code and find the real bottlenecks
- Optimize for speed, memory usage and latency
- Refactor messy or legacy C++ into clean, maintainable code
- Improve multithreading and concurrency
- Modernize old code to current C++ standards (C++11/14/17/20)
I measure before and after, so you see the actual improvement not just promises.
You get the optimized code, a summary of what changed and why, and benchmark results.
I work asynchronously and reply to every message within 3-12 hours. Send me your code and tell me what feels slow I'll review it and tell you honestly what can be improved before you order.

FAQ
How much faster will my code be?
It depends entirely on the code. I profile it first and tell you what's realistic before you order — I never promise numbers I can't back up.
Will the optimized code still behave the same?
Yes. Optimization must not change correctness. I test the behavior before and after, and your test cases keep passing.
Do you sign NDAs?
Yes, I'm happy to keep your code confidential.
