Freelancer Overview

I'm a bilingual (English–Spanish) AI Data Specialist with hands-on experience in multimodal annotation, including speech, text, and image data. My expertise covers paralinguistic labeling (tone, sentiment, emotion, and intention), audio segmentation and quality review, entity classification, and visual object detection. I've also supported fine-tuning and evaluation tasks by verifying factual accuracy, assessing AI safety compliance, and ensuring linguistic and cultural consistency in multilingual content. My diverse background enables me to adapt to a wide range of annotation frameworks and quality standards for AI training and evaluation.
