Worked on the JetBrains/intellij-community repository to enhance the IDE’s editor and web content integration. Focused on developing a new method for retrieving the current file in the editor and improving the flow for opening text editors, using Kotlin for both UI and backend development. Integrated a new JCEF UI Adapter to streamline web content interaction within the IDE, and refactored the JCefUiAdapter to improve encapsulation and robustness. Addressed split-mode edge cases, such as handling previews with null examples and refining OpenAPI and Swagger keyword detection, contributing to greater stability and maintainability in remote and UI development environments.
