Wu Dexin

Compiler Optimization Expert at Kuaishou

Compiler Optimization Expert at Kuaishou with over six years of experience in C++ development and compiler technology. He specializes in compiler middle- and back-end optimization, intelligent resource allocation under complex constraints, and profile-guided optimizations based on runtime feedback, with a deep understanding of compiler theory and practice. He led the development of China’s first commercially deployed P4 network compiler system, overcoming multiple technical bottlenecks and delivering an efficient compilation solution for network data processing. Actively contributing to the LLVM open-source community, he proposed and implemented an innovative solution to address industry pain points in Propeller optimization—specifically its sensitivity to compiler flag changes and outdated profiles—resulting in significant performance gains for large-scale Kuaishou service projects.
