Mikhail Khokhlov
Worked on enhancing the stability and reliability of the google/perfetto trace processing pipeline by addressing critical bugs that caused DCHECK crashes and test fragility. Focused on updating Python-based table definitions and C++ data access logic to ensure correct handling of trace data, particularly during export and finalization phases. Improved cross-platform test infrastructure by refining Windows CI workflows and simplifying test traces, which reduced flakiness and accelerated development feedback. Demonstrated disciplined debugging, build system configuration, and continuous integration practices. The work resulted in more robust trace processing and safer iteration for profiling workloads, with a strong emphasis on defensive programming and data modeling.
