PROFILE
Mikhail Khokhlov
During two months contributing to google/perfetto, Khokhlov focused on enhancing the stability and reliability of the Trace Processor by addressing critical crash scenarios. He updated Python-based table definitions and C++ data access logic to fix DCHECK crashes, ensuring correct handling of trace data during processing and export. His work included aligning column access with finalization phases and improving cross-platform test infrastructure, particularly for Windows CI. By refining data modeling and debugging workflows, Khokhlov reduced crash risk and improved test robustness, enabling safer feature iteration. His disciplined approach demonstrated strong skills in C++, Python, continuous integration, and trace processing.
