Summary
🤩
Rockstar🎓
Top SchoolLu-hsuan Chen is a systems software engineer with a decade of hands-on experience and 4+ years focused on low-level performance engineering, CPU architecture, SIMD and Linux internals. He has shipped kernel and driver patches at scale, optimized networking and storage components, and improved production clustering performance (notably a CRC16 multi-byte lookup optimization that boosted RPS and latency). An active open-source contributor, he has improved simdjson, sse2neon and semu—implementing cross-ISA intrinsics like _rdtsc and adding C++20 DOM ranges tests—bridging deep systems knowledge with reproducible community-grade engineering. His background spans virtualization, USB/guest audio device VirtIO work, distributed infrastructure automation and real‑time analytics dashboards, showing a rare mix of firmware-level debugging and higher-level cloud tooling. Based in New Taipei, Taiwan, he’s open to roles in system software, performance engineering and infrastructure where low-latency, platform-aware optimization matters.

Contributions summary:Lu-hsuan implemented and tested the `_rdtsc` function, which retrieves the processor's time-stamp counter. They modified existing test cases and added new ones for `_rdtsc` to ensure its functionality. Additionally, the user refactored the code by changing the style of the `asm volatile` keywords to align with the project's coding style. They also simplified some test cases.
