Worked on build system reliability and patch workflow automation across the OpenXiangShan/buildroot and home-assistant/buildroot repositories, focusing on embedded systems development and configuration management. Addressed a critical U-Boot rock5b build issue by ensuring proper util-linux dependency handling, which resolved missing header errors during specific configurations. Enhanced patch quality by integrating patch-aware checks and per-patch validation into the Buildroot workflow, streamlining submission processes. In response to a gnutls update, refactored the pqc-hybrid-kx representation in C to fix Clang compile errors and expanded test coverage, maintaining CI stability. Utilized C, Python, and scripting to support robust, maintainable build pipelines.
