Worked on the google/perfetto repository, focusing on enhancing the robustness and security of trace data parsing workflows. Addressed a critical bug in the Proto Trace Tokenizer by implementing a defensive guard against unsigned integer overflow when calculating total size, including the header. This C++ development effort improved reliability for large-scale trace processing, reducing the risk of overflow-related crashes or data corruption. The work centered on performance optimization and bug fixing rather than feature development, resulting in improved data integrity for users handling large traces. The contribution demonstrated careful attention to defensive programming and secure handling of trace data in C++.
