PROFILE

John Chrosniak

During four months, Jacob Chrosniak engineered robust platform and tooling enhancements across the usdot-fhwa-stol/carma-platform and carma-analytics-fotda repositories. He migrated the CARMA platform from ROS 2 Foxy to Humble, refactored CI/CD pipelines using Docker and CMake, and standardized configuration naming to streamline upgrades and reduce maintenance. Jacob also delivered GNSS-only localization with a fixed offset, simplifying deployment in GNSS-rich environments. For carma-analytics-fotda, he improved accessibility in visualization scripts and developed map generation workflows using Python and XML, enabling Lanelet2 and XODR transformations. His work emphasized maintainability, accessibility, and integration, demonstrating depth in configuration management and geospatial data handling.

Work History

May 2025

3 Commits • 2 Features

May 1, 2025

May 2025: Focused on accessibility improvements for visualization tooling and on engineering map generation workflows to support CARMA Cloud integration. The month delivered two key features: 1) CDA1Tenth visualization scripts enhanced for 508 accessibility and improved clarity of plot lines and labels, and 2) Map tooling enabling Lanelet2-based two-lane map creation and XODR map transformation with accurate geoReference handling for OSM/XODR formats. These workstreams collectively enable broader user access, streamlined data-to-decision pipelines, and smoother CARMA Cloud deployments. No high-priority bugs reported this month; the emphasis was on delivering robust features and reinforcing data workflows.

April 2025

1 Commits • 1 Features

Apr 1, 2025

April 2025: Delivered a simplified GNSS-based localization mode for the carma-platform by switching to GNSS-only with a fixed offset and consolidating localization configuration into a single parameter. This reduces localization complexity, improves predictability in GNSS-rich environments, and speeds deployment.

December 2024

3 Commits • 1 Features

Dec 1, 2024

December 2024: Delivered a major platform upgrade for CARMA by migrating from ROS 2 Foxy to Humble, stabilizing the CI/build pipeline, and standardizing configuration naming. This upgrade reduces future upgrade friction, improves runtime stability, and speeds up Docker-based CI cycles.

November 2024

3 Commits • 2 Features

Nov 1, 2024

November 2024 monthly summary focusing on business value and technical outcomes: Completed naming consistency and branding updates across two repositories, enabling stable demos and easier maintenance. Focused on CDA1tenth naming consistency (C1T → CDA1tenth) and TRB demo readiness, with careful refactors to preserve core functionality. The changes improved cross-repo alignment, reduced configuration drift, and streamlined future development and demonstrations.
