Freelancer Overview

I am a data annotation and AI labeling specialist with over 10 years of experience supporting machine learning and computer vision projects. My expertise spans image, video, audio, and text annotation using tools like Labelbox, CVAT, and YOLO-based frameworks. I have consistently delivered high-quality datasets for object detection, tracking, and speech recognition, ensuring accuracy above 98% through rigorous QA processes. My work includes annotating over a million objects for autonomous driving and surveillance, leading large-scale video tracking projects, and contributing to NLP sentiment classification with top inter-annotator agreement. I am skilled in dataset preparation, cleaning, taxonomy design, and collaborating with ML teams to refine guidelines and improve data quality across diverse domains. Fluent in English, Spanish, French, and Portuguese, I thrive in remote, multicultural AI projects.
