Worked on the coopcycle-web repository to enhance dashboard stability by addressing a critical bug in the order card component. Focused on front end development using React and JavaScript, the developer implemented a null-safe guard with optional chaining to handle cases where customer data might be missing. This defensive coding approach in TypeScript prevented crashes caused by null dereferences, ensuring the dashboard could reliably render icons and usernames even when customer information was incomplete or absent. The solution improved UI resilience and maintainability, reducing white-screen incidents for guest and API orders while supporting a smoother operator experience in the foodtech dashboard.
