PROFILE
Eric Seckler
Worked on the google/perfetto repository, focusing on enhancing trace data reliability and power analysis across Android and Linux environments. Delivered features such as improved power rail mapping for new Pixel devices and sandboxed thread ID handling for Linux, ensuring accurate trace attribution and backward compatibility. Addressed critical bugs by refining SQL-based power calculations and stabilizing trace event processing, which improved test reliability and cross-component data assembly. Utilized C++, SQL, and Protocol Buffers to implement robust solutions for trace processing, system programming, and embedded analytics, emphasizing correctness, edge-case handling, and maintainability in both feature development and bug resolution efforts.

Jan 1, 2025January 2025 monthly performance summary for google/perfetto. Focused on Android Probes and power-rails analytics. Delivered feature enhancement for Android Probes: Enhanced Power Rail Mapping for P23/24; improved robustness of mapping across Pixel generations to ensure accurate power rail identification in trace data. Fixed critical bug: Android Power Rails average power calculation; replaced division by near-zero duration with nanoseconds-based scaling to avoid NULL results. Commits associated with these changes include cc75c2555ddfd6bc678cfed36d6fe66d1789d673 and ab5c6f1b2ddc55ad5c5cadde12c61391d571e89b. Overall impact includes more accurate trace power data, cross-device reliability, and faster diagnostics for power-performance analysis. Technologies demonstrated include Android probes module updates, SQL-based power calculations, data instrumentation, and robust edge-case handling across Pixel devices.
