Software engineer at Preferred Networks, Inc.

I am ...

SIMD / vectorization enthusiast, good at C and Rust with x86_64 / arm64 intrinsics.
- enjoying re-designing and tuning various algorithms for modern rich processors (with OoO, SIMD, and multi-level cache).
Sometimes work with Python, C++, shellscript, R, and so on...
