About me
I build and optimize performance-critical software in C, C++ and Rust, with a focus on low latency, memory efficiency and measurable results.
My work covers profiling and hot-path optimization, cache-aware code, SIMD, multithreading, native extensions, networking and low-level debugging.
I work from evidence: benchmark first, isolate the bottleneck, make targeted changes, then verify correctness with tests, sanitizers and reproducible before/after measurements.
Deliverables are clean, documented and ready to review in Git.
