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.
