About this gig

Is your C++ application running slowly, using too much memory, or suffering from memory leaks?

I'm a Senior C++ Software Engineer with nearly 20 years of professional experience in desktop and systems development.

I can help you with:

  • Finding and fixing memory leaks
  • Profiling CPU and memory usage
  • Identifying performance bottlenecks
  • Optimizing algorithms and data processing
  • Improving C++ and Qt application performance
  • Investigating crashes and resource management issues
  • Measuring performance before and after changes

I work with modern C++, Qt, STL, CMake, and debugging and profiling tools on Windows and Linux, with cross-platform experience.

My approach is straightforward: reproduce the problem, measure it, identify the cause, make a focused improvement, and verify the result.

Please message me before ordering so we can agree on the scope and expected outcome.

Senior C++/Qt desktop engineer with 20 years of experience fixing and optimizing Windows, Linux, and macOS apps. I work with C++17–23, Qt 5/6, QML, CMake, SQLite, multithreading, cryptography, and performance profiling. I resolve crashes, memory leaks, freezes, build failures, cross-platform issues, and slow startup. Results include 92% shared code across platforms, startup reduced from 8s to 1.2s, and software used by 50,000+ users. You’ll receive a clear diagnosis, focused fix, tested changes, and technical notes. Please send the issue, OS, Qt/compiler versions, and logs.
