About this gig

Is your code crashing, throwing errors, or behaving weirdly?

I'll dive in, find the root cause, and fix it cleanly and fast.

What I handle:

  • Segmentation faults / crashes
  • Memory leaks and corruption
  • Undefined behavior
  • Compile errors and linker errors
  • Runtime errors
  • Logic errors and off-by-one mistakes
  • Race conditions / data races
  • Buffer overflows and null pointer dereferences

What you get:

  • Working, tested code
  • A short explanation of what went wrong
  • Clean fixes no messy patches

Send me your code + the error message. I'll get back to you with a quote.
