Summary
👤
Senior🎓
Top SchoolXinyue Lu is a software engineer with 14 years of experience building real-world web applications and performance-critical back-end systems, currently based in Portland, Oregon. She combines full-stack web skills (PHP, Ruby on Rails, MySQL, HTML5/CSS3, JavaScript frameworks) with low-level optimization expertise in C/C++/ASM and SIMD-accelerated audio routines. Her open-source contributions include substantive encoder and media-processing work on notable projects like x265 and AviSynthPlus, where she improved CLI behavior, bitstream handling, and SIMD-optimized audio converters. At Kubisys and prior roles she has designed production systems, managed LNMP stacks, and delivered prototypes for institutional partners, demonstrating a knack for both product-facing features and infrastructure. A quick learner and pragmatic problem solver, she often bridges gaps between high-level web stacks and performance-sensitive native code.

Contributions summary:Xinyue primarily contributed to the x265 video encoder project, modifying the command-line interface (CLI) and core encoding logic. Their work included preventing the operating system from entering standby mode during encoding, unifying logging functions, and moving raw bitstream output to a separate file. They also refactored the code to handle timebase and PTS correctly, and addressed issues related to the annex_b format for bitstream output, enhancing the versatility of the encoder.
