Freelancer Overview

I am a bilingual English–Portuguese professional specializing in AI training data, prompt engineering, and data labeling. With experience creating and reviewing prompts and responses for large language models (LLMs), I ensure outputs are accurate, contextually relevant, and linguistically precise. Skilled in NLP, data annotation, and quality evaluation, I bring both technical expertise and linguistic insight to improve AI systems and enhance their real-world performance.
