About this gig

I specialize in C and C++ debugging, optimization, and code review for systems-level software.

I don't do basic homework or generic scripts. I work on real code (Linux applications, kernel modules and performance-critical libraries)

What I can do for you:

  1. Bug Fixing: Segmentation faults, memory leaks, undefined behavior, data races, and locking issues (deadlocks, priority inversion)
  2. Optimization: SIMD vectorization, cache-friendly data structures, and algorithmic improvements with benchmarks to prove the speedup
  3. Code Review: In-depth analysis using static analysis tools, and manual inspection for memory safety and logical errors
  4. Linux Systems: USB drivers, kernel patches, syscalls, and build systems (Make, CMake, compile_commands.json)


My background:

  1. Written USB linux drivers
  2. Built SIMD-optimized image processing libraries in C
  3. Developed custom static analysis tooling and LLVM passes in C++
  4. Contributed to open-source projects


You can send me the code and a description of the problem. I will send back working, tested code with a clear explanation of what was wrong and how i fixed it

C/C++ systems programmer specializing in Linux, low-level debugging, and performance. I've written and patched USB kernel drivers (isochronous endpoints), built SIMD-optimized image libraries (AVX2/AVX-512), and developed static analysis tooling including LLVM passes. What I do: Fix segfaults, memory leaks, data races, and locking bugs Optimize with SIMD, cache-friendly data structures, and better algorithms Code review for UB, memory safety, and performance bottlenecks Linux kernel modules, device drivers, system utilities
