Tell me about a time you received critical feedback on your frontend code or a UX decision. What was the feedback, how did you respond, and what did you change as a result?

On a payments page I shipped a compact checkout flow that our PM praised for fewer clicks, but in code review a senior designer and accessibility engineer flagged keyboard and screen-reader issues and a 3-column layout that confused users. I took the feedback seriously: I paired with the designer for two days, rewrote the DOM order for logical reading, added aria labels, and simplified the keyboard tab order. I also wrote unit and end-to-end tests that ran axe checks and keyboard navigation tests. After changes conversion stayed the same but accessibility score jumped from 72% to 98% and reported support tickets dropped 60% over the next month. I learned to solicit cross-discipline reviews earlier and now include accessibility checks in our PR checklist.
