TextI have 9 years of experience as an editor, writer, and translator, with a strong focus on accuracy, consistency, and attention to detail. Over the past year, I have transitioned into AI-focused work as an AI trainer and data annotator, evaluating AI-generated responses, labeling text data, and contributing as a linguist on speech annotations. I am a native Spanish speaker from Chile and have advanced proficiency in English. I hold a BA in Linguistics, with training in syntax, semantics, and discourse analysis. I also have a Bachelor of Education, which supports my ability to apply rubrics consistently and provide clear feedback.
Label over 32,500 query-item pairs for an e-commerce platform. In this role, I assess the relevance of each pair by analyzing titles, images, and product copy to improve search relevance and rankings.
Correct and validate 2,500+ pre-annotated speech descriptions in Spanish, refining notes on audio quality, voice traits, and utterance delivery (such as rhythm, stress, and emotional tone) for AI recognition and generation assistants.
Create 100+ prompts and evaluate 500+ AI responses in Spanish, providing feedback in English to optimize instruction adherence, output safety, factual correctness, and writing quality. The projects focused on enhancing AI's ability to respond effectively to diverse prompts, covering categories such as education, health, sports, and life sciences, among others.
