Describe a time when you had to learn a new technology or framework quickly to deliver a project. What steps did you take to get up to speed, how did you apply what you learned, and what was the outcome?

On a recent rotation I was handed ownership of a customer-facing portal that needed to be rebuilt using React + TypeScript within four weeks to meet a business milestone. I spent the first three days on focused learning—two LinkedIn Learning courses, the official TypeScript handbook, and a CodeSignal coding kata—then built a working prototype in 48 hours. I paired with a senior engineer (my assigned buddy) for API patterns and accessibility decisions, wrote unit and integration tests, and ran three peer reviews. We shipped the feature in week three, reduced initial page load by 40%, and cut post-release bugs by 60% in the first month. The portal supported a 25% increase in task completion for users and the codebase hit 85% test coverage.
