Freelancer Overview

I am a detail-oriented data annotation and AI training professional with hands-on experience in labeling and validating text, image, and linguistic data for machine learning projects. I have worked extensively on platforms like Clickworker, UHRS, Appen, and Microworkers, where I performed content classification, entity tagging, and dataset validation, consistently maintaining high accuracy and quality standards. My expertise includes applying complex project guidelines, especially those involving Portuguese linguistic rules, and ensuring labeling consistency across large datasets. I am highly organized, reliable, and able to deliver results within deadlines, with strong skills in online research, quality assurance, and remote task management. I am fluent in Portuguese and have professional working proficiency in English, making me adaptable to a variety of annotation projects.
