Mike Tu developed a feature for the ir-engine/ir-engine repository that prevents users from accidentally deleting the currently active editor scene, addressing a key data loss risk in editor workflows. He implemented UI logic in React and TypeScript to dynamically disable the delete option when a scene is active, ensuring destructive actions are gated by the editor’s state. This approach improved user experience and aligned with product safety requirements by reducing the chance of accidental data loss. The work demonstrated proficiency in front-end development and UI state management, with clear traceability through linked commits and readiness for review and quality assurance.
