Freelancer Overview

I am a language professional with over seven years of experience in linguistic analysis, semantic evaluation, and content review, now focusing on AI training and language data annotation. My expertise spans assessing written and spoken language for grammar, semantics, clarity, and contextual appropriateness in Portuguese and English. I have a strong track record of providing consistent, guideline-driven feedback and ensuring high-quality language data, making me skilled in tasks such as data labeling, annotation, and quality assurance for NLP projects. My international experience and background in education further enhance my ability to adapt content for diverse audiences and support AI systems in understanding linguistic nuances.
