Walk me through a model you shipped: framing, data, evaluation, and measured impact.

Answer with a concrete example using the STAR method (situation, task, action, measurable result). For a Data Scientist, lead with the result and the metric you moved, then how you achieved it — the same achievement belongs on your CV.

How do you choose an evaluation metric, and when is accuracy misleading?
