- Implemented a multithreaded model using executeOnPooledThread and invokeLater to handle time-consuming tasks asynchronously and avoid blocking the UI thread.
- Embedded a React frontend using JCEF and established a frontend-backend communication bridge with CefMessageRouter, enabling directory scanning and refactoring task initiation.
- Utilized IntelliJ's VirtualFile and VfsUtilCore to recursively scan project directories and return the generated refactoring suggestions in JSON format for frontend display.
- Modified file content accurately after receiving user confirmation, including removing code blocks based on given line numbers and adding new functions to target files, leveraging IntelliJ's VirtualFile and WriteCommandAction to complete the refactoring operation.
- Addressed Java 17 and Java 21 compatibility issues by integrating with backend APIs via HTTP, ensuring smooth cross-version functionality.
Emergency Social Network 1/2024–5/2024 -Campus project training program
Tech Stack: JavaScript, HTML, CSS, Bootstrap
