Developed and integrated Arm CPU telemetry capabilities into the google/perfetto repository, focusing on a dedicated UI plugin for loading, inspecting, and validating Arm CPU specifications. Leveraged TypeScript and front end development skills to create a new interface for analyzing Arm CPU specs, persisting them across sessions, and enabling trace-load integration that computes and registers per-CPU metric tracks from PMU counter data. Built infrastructure for generating metric tables and views, allowing users to perform detailed CPU performance analysis directly in the UI. The work emphasized full stack development, with ongoing stabilization to ensure robust Arm telemetry integration and streamlined diagnostics.
