Freelancer Overview

I have extensive experience in AI operations and data annotation, with a strong focus on delivering high-quality training data for machine learning systems. At Scale AI, I have worked on complex data labeling projects across text, image, video, and multimodal domains, consistently ensuring accuracy and guideline adherence as both a Senior Reviewer and Oracle contributor. My background includes designing and deploying custom AI systems, leading operational audits, and preparing data to optimize system performance and reliability. I am skilled in data analysis, data cleaning, and evaluating model outputs for instruction-following and reasoning quality. I also have hands-on experience with vibe coding workflows, using tools like Cursor to rapidly prototype, test, and refine AI-powered applications and internal tools. My experience spans computer vision, NLP, and multimodal reasoning tasks, and I bring a detail-oriented, risk-aware approach to every project I undertake. I am also fluent in Spanish, which enables me to contribute to multilingual data initiatives.
