Worked on the InfraWatch-inc/web-data-viz repository to enhance the authentication user interface, focusing on improving onboarding and user experience consistency. Consolidated the registration and login flows by standardizing back navigation and refining the styling of Sign Up and Login buttons for clearer semantics. Employed CSS and HTML to implement these changes, ensuring a balanced and intuitive navigation layout across authentication screens. The updates included improved semantic labeling for authentication actions, which aimed to reduce friction during onboarding. Delivered these enhancements through a series of targeted UI commits, establishing a foundation for future usability improvements and maintaining a focus on front-end development best practices.
