PROFILE
Alexis Jacomy
Worked on the OpenRailAssociation/osrd-ui repository to enhance chart rendering and user experience for railway visualization tools. Focused on improving the fidelity and interactivity of the spacetime chart by implementing DPR-aware rendering, bidirectional path simulation, and high-DPI performance optimizations using React, TypeScript, and the Canvas API. Addressed cross-browser inconsistencies by introducing a helper for crisp line coordinates, ensuring reliable waypoint line visibility across browsers like Firefox. Aligned Storybook styling for consistent UI previews and refactored components for maintainability. These efforts improved chart readability, reduced visual artifacts, and established a robust foundation for future data visualization features and performance enhancements.
