Worked on the google/perfetto repository to enhance build and test stability by addressing critical bugs in C++ code. Focused on resolving an ODR violation in RawMemoryGraphNode by refactoring string constants as static constexpr in headers, ensuring single definitions across translation units and stabilizing ASan builds. Additionally, improved test reliability by preventing crashes from null pointer dereferences in MessageTest.MessageHandle, introducing assertions to eliminate undefined behavior under sanitizer configurations. Collaborated with other contributors to align with CI and QA hardening efforts. Leveraged expertise in C++, build systems, debugging, and testing to deliver robust, maintainable improvements to the codebase.

Apr 1, 2025April 2025 Monthly Summary for google/perfetto: Implemented a critical ODR violation fix in RawMemoryGraphNode to stabilize ASan builds. By moving string constants to static constexpr in the header and defining them to ensure a single definition across translation units, we eliminated multiple-definition issues and associated runtime errors. The work aligns with commit e99362e3256d505ff48d6aba394430de5e0fcf13 (trace_processor: Fix ODR violations (#1213)).
