Contributed to the DragonOS-Community/DragonOS repository by developing and refining core system features over a three-month period. Focus areas included kernel signal handling, user-space timer management, and robust process initialization. Applied expertise in Rust, Assembly, and shell scripting to implement timer system calls, enhance signal stack handling for multi-threaded environments, and improve filesystem permission logic. Addressed bugs affecting CPU time accounting, process stability, and user login reliability, particularly on FAT-formatted targets. Refactored code for maintainability and clearer separation of concerns, resulting in more reliable user sessions, improved terminal UX, and reduced technical debt across embedded and multi-user Linux deployments.

Jan 1, 2026January 2026: Focused on stabilizing the user login path and HOME initialization for DragonOS. Delivered critical fixes to BusyBox-driven HOME resolution and FAT filesystem inittab startup, improving reliability of user sessions and boot/login flow across embedded targets. This work enhances system stability, reduces login-related support issues, and strengthens the user onboarding experience on FAT-formatted deployments.

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.
