PROFILE
Yohai Gevim
Worked on the google/perfetto repository to enhance TAR trace ingestion by implementing support for base-256 size fields, robust error handling, and correct directory entry processing in C++. Improved the archive reader’s reliability by detecting malformed inputs and ensuring directories are skipped, reducing load errors for users. Addressed archive entry sorting and deduplication by introducing strict ordering logic, which improved data integrity and downstream analytics. Delivered a memory-safety fix for large TAR files, validating file sizes to prevent overflows and memory corruption, especially in browser and 32-bit environments. Demonstrated expertise in C++, file parsing, memory management, and system programming throughout these contributions.
