Worked on expanding front-end operational points for the OpenRailAssociation/osrd repository, delivering support for a new railway axis and enhancing the display and handling of operational data. The approach involved updating the operational points list and performing targeted refactors, such as renaming a key file and related variables to improve code clarity and maintainability. This work, implemented using React and TypeScript, broadened the scope of data available on the front end and laid the groundwork for future analytics and operational visibility. The changes were delivered as a single, traceable commit, reflecting a focused and maintainable approach to front-end development in JavaScript.
