Han-Kuan Chen
Summary
🤩
RockstarHan Chen is a compiler engineer with seven years’ experience specializing in C++, LLVM, RISC-V, and multithreaded programming, currently maintaining SiFive Recode as part of the LLVM project. He focuses on compiler optimizations—particularly SLP vectorization—having refactored interfaces and cost models to add vector instruction support in CallInst and SelectInst. His background includes AI compiler performance work at Bitmain and a solid academic foundation from National Tsing Hua University, with international exposure as an exchange student. Based in Hsinchu, Taiwan, he blends systems-level rigor with practical toolchain contributions to widely used open-source infrastructure.
