Barbara Hernandez

At Uber, I design prompts and evaluate generative AI text and voice responses, turning expert judgment into rubrics and golden answers for model training. I manage high-volume evaluations, safety testing, simulated scenarios, and Voice AI analysis to improve accuracy, tone, and usefulness.

I've also investigated fraud and compliance risks at Uber, interpreted sensitive medical and legal conversations at Language Line, and led teams across sales, collections, and quality operations. I'm a native Spanish speaker with C1 English, bringing analytical judgment, clear communication, and leadership to complex, people-centered work.
