Bingqian Liu
Contributed to the google/perfetto repository by developing advanced Android memory heap analysis features, focusing on graph scanning and class relationship tooling to enhance data quality and modularity. Leveraged SQL and trace processing skills to introduce new modules and macros for consistent class relationship analysis, while refactoring existing components to improve performance and reliability. Extended memory profiling capabilities to better support Kotlin-based workloads by updating libcore filter patterns, enabling accurate categorization of Kotlin core types. The work emphasized scalable, maintainable solutions for heap data analysis, demonstrating expertise in Android development, build systems, and database technologies over a focused two-month period.
