PROFILE
Chris Wiseman
During January 2025, contributed to the google/perfetto repository by developing an Energy Usage Visualization feature that enhances energy profiling capabilities. This work introduced a new UI column and an accompanying SQL metric to display each thread’s and process’s energy consumption as a percentage of total energy, allowing users to quickly compare energy efficiency across workloads. The implementation involved TypeScript for UI development and SQL for metric calculation, demonstrating skills in data visualization and performance analysis. By improving observability into energy usage, the feature supports data-driven optimization decisions, facilitates identification of energy hotspots, and enables more effective power-cost management for users.
