I will optimize your cpp code for speed and memory efficiency
Danilo Guerin
About this gig
Is your C++ program too slow, eating too much memory, or struggling to scale? I'll find the bottlenecks and make it fast.
I'm a low-level systems developer. I've built memory analysis tools from scratch, so I understand performance where it actually happens: CPU cache behavior, memory layout, allocations, and what the compiler really does with your code.

I solve the C++ problems most people can't: hard crashes, memory leaks, slow code, and weird low-level behavior. I work with modern C/C++ on Linux, with hands-on experience in reverse engineering, memory analysis, and performance optimization. I'm a Computer Engineering student and I treat every job as a real technical problem to solve — not just "make it compile," but understanding why it works. You get clean, explained code delivered on the agreed deadline. Send me the problem and I'll tell you honestly if I can fix it.
FAQ
What I optimize:
Slow functions and hot loops (algorithmic + micro-optimization) Excessive memory usage and allocation overhead Cache-unfriendly data structures (AoS → SoA, layout redesign) Unnecessary copies, missing move semantics, string handling Build flags and compiler settings (GCC/Clang, LTO, -O levels)
How it works
Send me your code and tell me what's slow (or let me find it) You get optimized code + before/after benchmark numbers + explanation of every change
Why Me
I measure, I don't guess. Every optimization comes with a benchmark proving the improvement. No "it feels faster" — you'll see the numbers.
