Freelancer Overview

I bring over three years of experience in content moderation and data annotation, working directly with AI training datasets for some of the most demanding platforms. My work has included nuanced labeling tasks involving image, text, and video content, with a strong focus on quality, consistency, and emotional intelligence. I have developed a sharp eye for recognizing subtle emotional cues, context shifts, and cultural nuances—skills that are essential for training empathetic and accurate AI systems. With a background in engineering and a deep analytical mindset, I excel at identifying patterns, spotting inconsistencies, and understanding complex guidelines quickly. I'm also fluent in both English and Spanish, which allows me to annotate and QA multilingual datasets effectively. My strength lies in combining precision with a human touch, ensuring that AI learns from data that is not only clean—but meaningful.
