PROFILE
Michael Behrisch
Over 18 months, contributed to the eclipse-sumo/sumo repository by engineering robust simulation, packaging, and CI infrastructure. Developed and maintained cross-platform build systems, implemented data export pipelines using C++ and Python, and expanded support for formats like Parquet and CSV. Enhanced simulation fidelity through API development, memory management improvements, and feature-rich test automation. Addressed hundreds of bugs and optimized workflows for reproducible, reliable releases across Linux, Windows, and macOS. Leveraged technologies such as CMake, Docker, and CI/CD pipelines to streamline deployment and accelerate feedback. The work emphasized maintainability, code quality, and broad compatibility for large-scale, multi-language simulation environments.

Jun 1, 2026June 2026 performance summary for eclipse-sumo/sumo: Delivered a key feature to improve projection data path resolution in GeoConvHelper by basing search paths on the SUMO_HOME environment variable, enhancing deployment flexibility and reducing configuration errors. No major bugs fixed this month. Impact: more robust projection parameter handling in production pipelines and easier onboarding of new environments. Technologies demonstrated: environment-variable driven configuration, GeoConvHelper refactor, commit dd66a7568024795b88fedf6c91d54960a91ce6e6.

Apr 1, 2026April 2026 monthly summary for eclipse-sumo/sumo: Focused on improving build reliability and reproducibility for the repository. Delivered reproducible installs by pinning dependency versions (libparquet-dev, Apache Arrow, and Parquet libraries) in installation scripts, ensuring stable builds across environments. This work reduces environment drift, lowers onboarding friction, and supports stable CI and customer deployments.
