I'm particularly skilled at translating ambiguous business questions into measurable ML problems. At [Previous Company], I collaborated with stakeholders to reframe a churn prediction challenge, ultimately discovering that [specific insight] was the key driver.

I'm excited about [specific technical or mission-driven aspect of the role], and I'm confident I can contribute to [Company]'s data maturity immediately. I'd welcome the chance to discuss how my experience scales to your challenges. Best regards, [Your Name]
