About

I am a Spanish language specialist focused on AI content and audio evaluation. I review AI-generated Spanish text and speech for linguistic accuracy, clarity, and naturalness, applying a strong eye for pronunciation, tone, pacing, and intelligibility. I also perform guideline-based reviews and deliver clear, actionable written feedback to support dataset improvement and model refinement. I work remotely in asynchronous environments, collaborating with teams to improve dataset quality and accessibility for real Spanish-speaking users.

Based in Argentina, I bring experience in manual QA testing and language quality assessment to multidisciplinary AI and dataset projects. I enjoy identifying edge cases, documenting insights, and communicating effectively to enhance user experience and inclusivity while maintaining rigorous linguistic standards.
