Worked on the adobe/aem-core-forms-components repository to deliver a UI Theme Editor for core components, focusing on enhancing the theming and styling experience across the user interface. Leveraged Java and XML to implement configurable theme options, update error and success state handling, and expand styling coverage for elements such as buttons, checkboxes, and input fields. Ensured consistency in UI feedback by refining error messaging selectors and updating theme configurations. Completed comprehensive testing for new theming features, which reduced the risk of UI drift and supported faster design system updates. Emphasized front end development and UI/UX design throughout the project.
