Worked on enhancing thread-safety in the EditorWindow component of the JetBrains/intellij-community repository, focusing on backend development with Kotlin. Addressed a concurrency issue by switching the coroutine dispatcher from the UI thread to the Event Dispatch Thread (EDT), thereby reducing the risk of UI-thread contention and improving overall application stability. This targeted bug fix involved diagnosing the root cause of potential UI freezes and implementing a solution that prevents reads on the UI thread, aligning with ongoing performance and reliability goals. Demonstrated strong concurrency management skills and delivered the change end-to-end, contributing to a more robust user experience for IntelliJ users.
