During a two-month period, BQL enhanced Android memory analysis capabilities in the google/perfetto repository by developing advanced heap graph scanning and class relationship tooling. Leveraging SQL and Android development skills, BQL introduced a modular heap_graph.class_relationship module and refactored existing components to improve performance and data quality. The work included removing null values from input tables to increase reliability and adding new SQL macros for scalable reporting. In a subsequent update, BQL extended heap graph categorization to accurately identify Kotlin core types, improving memory profiling for Kotlin workloads. The contributions demonstrated depth in trace processing, build systems, and database-driven analytics.
