Developed a new App Management CLI feature for the winapps-org/winapps repository, introducing the --add-apps option to the setup script to enable incremental application additions without requiring a full reinstall. This enhancement streamlined the app management process by allowing users to update their installations more efficiently. The work involved advanced shell scripting and command line interface development, with a focus on robust error handling to prevent conflicting commands and improve script reliability. By reducing deployment downtime and improving the user experience for app lifecycle management, the changes laid a foundation for more flexible and maintainable deployment workflows using Bash.
