Contributed to DragonOS-Community/DragonOS by developing and refining core operating system features over four months, focusing on kernel, filesystem, and user experience improvements. Leveraged Rust, Assembly, and Shell scripting to implement timer system calls, enhance signal handling, and introduce a colorful command prompt for better terminal usability. Addressed filesystem reliability by fixing permission logic and adding umask support, while also resolving user login and HOME initialization issues for embedded and FAT-formatted environments. Enhanced Ext4 filesystem flexibility with remount support and improved task scheduling robustness, applying concurrent programming and kernel development expertise to deliver more stable, maintainable, and user-friendly systems.

Dec 1, 2025December 2025 – DragonOS contributions focused on UX improvements, filesystem reliability, and process stability. Delivered three key items: a Colorful Command Prompt (PS1) enhancement for improved terminal visibility; a bug fix and feature addition for filesystem permissions (sys_mkdir logic fix and sys_umask); and kernel signal handling improvements that fix PID retrieval and signal-ignoring edge cases for init and multi-threaded contexts. These changes reduce permission-related issues, improve multi-user reliability, and enhance developer productivity via clearer prompts and robust process management.
