PROFILE
Pivouane (pierre Santamaria)
Over seven months, contributed to OpenRailAssociation/osrd by building and enhancing a range of frontend features focused on scheduling, time entry, and operational visibility. Developed interactive UI components such as editable time and duration inputs, margin editing cells, and train header forms, emphasizing robust validation and localization. Leveraged React, TypeScript, and CSS to implement state-driven interfaces, optimize rendering performance, and ensure data integrity. Integrated backend connectivity for real-time updates and introduced CI/CD validation steps using Helm and Kubernetes. Addressed UI reliability and routing accuracy, supporting both English and French users, and maintained high code quality through disciplined version control practices.

Apr 1, 2026April 2026 highlights for OpenRailAssociation/osrd: Delivered three core capabilities spanning UI, runtime performance, and deployment reliability. Margin editing in the times stops table provides an editable margin cell wired to the backend for real-time updates and data validation, improving scheduling accuracy and user experience. Train simulation loading optimization defers conflict fetching until all simulations are complete, resulting in faster perceived load times and smoother UX. CI validation for values.schema.json in the Helm chart pipeline adds a validation step to ensure the generated schema.json matches the expected output, increasing deployment reliability. Together, these efforts demonstrate end-to-end capability—frontend-backend integration, performance optimization, and robust CI/CD practices—delivering tangible business value through reduced scheduling errors, faster interactions, and more dependable deployments.
