Yevhen Kandyba developed a new Frequently Asked Questions section for the Duard4/goit-js-team-project repository, focusing on enhancing the user experience through improved self-service support. He implemented the feature end-to-end, creating the HTML structure, applying CSS for layout and visual consistency, and using JavaScript to build an interactive accordion that allows users to easily browse common questions and answers. The work was scoped to improve frontend usability without disrupting existing application flows. Over the course of the month, Yevhen concentrated on UI/UX, front-end development, and JavaScript interactivity, delivering a focused feature addition with clear, maintainable code and documented changes.
