A Chocolatey developer works with Chocolatey, a Windows package manager, to automate software setup processes. They write scripts to install, upgrade, configure, and uninstall software in a systematic way. They maintain these packages to ensure they are up-to-date and functioning as expected. This includes troubleshooting any issues, testing for reliability and performance, and integrating with other tools. Their goal is to streamline software management, making it easier to deploy applications across multiple Windows systems. They also often collaborate with other developers, sharing knowledge and contributing to the Chocolatey community.
