Tianyou Li

Worked on the intel/PerfSpect repository to deliver features that enhance system performance diagnostics and data management. Developed kernel lock analysis capabilities using Go and Linux command line tools, enabling detailed collection and analysis of lock contention data for improved observability. Introduced input validation and output format restrictions for lock command results, organizing performance data through temporary files and supporting cross-device reporting. Automated performance data archiving with a shell script integrated into the build process, streamlining data management and build-id handling. Focused on backend development, error handling, and scripting, the work emphasized maintainability, usability, and proactive performance optimization across platforms.
