PROFILE

Ivberg

Worked on reliability and telemetry features in the ROCm/onnxruntime repository, focusing on stabilizing session logging and error handling in C++. Addressed multi-session telemetry crashes by improving LogAllSessions robustness and enhanced ETW registration to prevent failures in low-integrity Windows environments. Refactored early initialization logging to use standard error streams, ensuring resilience when default loggers are unavailable. Later contributed to microsoft/perfview by expanding SourceLink source-file resolution, implementing two-phase matching and fixing regex parsing for both wildcard and exact path mappings. Emphasized backend development, concurrency, and unit testing to improve build reliability, diagnostic observability, and maintainability across diverse deployment scenarios.

February 2026: Focused on improving SourceLink source-file resolution in microsoft/perfview by implementing support for both wildcard and exact-path mappings. Introduced two-phase matching (exact first, then prefix) to align with SourceLink standards, fixed a regex bug that blocked parsing of multiple SourceLink mappings, and expanded tests to cover both mapping types. These changes improve build reliability and developer productivity by delivering accurate, deterministic source URL resolution across CI and local environments, and simplify traceability for larger repos.

This month focused on stabilizing Windows telemetry (ETW) and startup logging paths in ROCm/onnxruntime to reduce crash risk and improve telemetry reliability in enterprise/browser contexts. Delivered targeted fixes that harden initialization and ETW handling, enabling more robust operation in Edge-like low-integrity environments and ensuring crash-free fallback logging when a default logger is unavailable. These changes enhance platform stability, reliability of diagnostic data, and overall developer and operator confidence.
