PROFILE
Yohai Gevim
Yohai Gevim enhanced the google/perfetto repository by improving TAR trace ingestion reliability and memory safety. Over three months, he implemented base-256 size field support and robust directory handling in the TAR Trace Reader, enabling accurate parsing of complex archives. He addressed archive entry sorting and deduplication by designing a strict ordering algorithm, which improved data integrity for downstream analytics. Additionally, Yohai fixed memory corruption issues for TAR files larger than 4GB, ensuring safe processing across browser and 32-bit environments. His work leveraged C++ expertise in file parsing, error handling, and memory management, resulting in more stable and maintainable trace workflows.
