Worked on the eesast/web repository to deliver user interface enhancements focused on authentication and onboarding. Developed a dark and light theme toggle for the login page, allowing users to select their preferred visual mode and improving accessibility. Redesigned the IdentitySelection component layout to streamline usability and create a more visually consistent experience. Utilized React and styled-components to implement responsive layouts and maintainable component structures, with all changes tracked in a single, well-documented commit. The work demonstrated proficiency in JavaScript and TypeScript, addressing user experience friction during login and contributing to a more cohesive and adaptable frontend design system.
