PROFILE

Liujianqiang

Worked on linuxdeepin/dde-file-manager and linuxdeepin/dtkwidget, focusing on memory management, UI stability, and licensing compliance. Addressed memory leaks in core and UI components by refining Qt object ownership, improving resource cleanup during directory traversal, sidebar operations, and window shutdown. Enhanced build reliability and reduced risk of leaks by synchronizing type assignments and removing obsolete code. In dtkwidget, resolved a memory leak in DMainWindow by correcting QObject parenting and updated SPDX licensing headers to maintain legal accuracy. Utilized C++, Qt, and Linux systems programming to deliver targeted improvements that strengthened application stability, maintainability, and compliance over a two-month period.
