Freelancer Overview

I am a bilingual data science graduate with experience in data annotation, text classification, and AI training data for Natural Language Processing (NLP) applications. My work includes reviewing, correcting, and labeling both Portuguese and English content to improve AI model comprehension and accuracy. I am skilled in applying linguistic guidelines, ensuring high-quality and consistent annotations, and conducting content analysis for model evaluation. My technical expertise spans Python, R, SQL, Power BI, and key NLP tools such as nltk and scikit-learn. Through academic and freelance projects, I have contributed to NLP model training, chatbot development, and the analysis of medical and legal datasets, always maintaining strong attention to detail and data quality. I am comfortable working independently, meeting deadlines, and delivering reliable results for AI and data-driven projects.
