Summary
👤
Senior🎓
Top SchoolSergey Nenakhov is an independent consultant and performance-focused software engineer with 15+ years of experience accelerating algorithms for HPC, visualization, and broadcasting domains. He specializes in low-level CPU optimizations (SSE/AVX/AVX512, ARM-NEON/SVE), GPGPU programming (CUDA, HIP, oneAPI), and porting/modernizing legacy Matlab, Fortran, and C++ code into highly efficient implementations. Sergey combines practical profiling-driven advice with hands-on vectorization and parallelization work, and has improved real-world projects including plotting and build-system performance in notable open-source repos. Based in Oslo with an MEPhI master's in computer science, he uniquely blends rendering expertise (OpenGL/DirectX) with production-grade systems tuning for industries like oil & gas and video broadcasting.
