Worked on frontend UI improvements for the bigcommerce/cornerstone repository, focusing on refining the payment method settings. Addressed a bug involving duplicate IDs on the edit payment method page by consolidating multiple commits into a single, maintainable patch. Ensured the default payment method checkbox consistently reflected the correct state across forms, enhancing both usability and reliability. Improved accessibility by updating relevant attributes, making the payment method settings more user-friendly for assistive technologies. Utilized HTML and front end development skills with a strong emphasis on accessibility standards. The work contributed to a more consistent and accessible user experience within the payment workflow.
