Developed and delivered a deployment warning dialog for the HeyPuter/puter repository, focusing on detecting the presence of a .git directory during deployment. This feature, implemented using JavaScript and front end development skills, introduced a user-facing dialog that alerts users to potential risks such as exposing sensitive information or increasing deployment size. The dialog offers options to cancel, continue, or permanently disable the warning, enhancing user control and governance in the deployment workflow. The work emphasized UI/UX development principles, integrating pre-deploy validation to improve deployment safety and provide clearer guidance, ultimately supporting safer and more transparent production deployments for users.
