Worked on the microcai/gentoo-zh repository to deliver a focused set of package updates that enhanced system usability, security, and build reliability for Gentoo users. Leveraged Bash scripting and Gentoo ebuild expertise to upgrade and maintain packages such as Gemini CLI, Baidu Net Disk, Bilibili video client, WeChat, and qbittorrent-enhanced. The work involved updating manifests, renaming ebuilds, and aligning with new URL structures to ensure smooth upgrade paths. No bugs were reported during this period, reflecting careful attention to detail and maintenance. All changes were completed within one month, emphasizing reliability and adherence to Gentoo packaging standards.
