Freelancer Overview

I have hands-on experience as a linguistic annotator, where I specialized in qualifying psychological behaviors, tone, intent, and meaning in both Portuguese and English transcripts. My work involved evaluating AI-generated transcripts for linguistic correctness, sentiment, and clarity, ensuring high-quality training data for NLP applications. I am highly detail-oriented and skilled in data analysis using tools such as SPSS, Excel (with VBA), Power BI, SQL, and Python. My background also includes market research and qualitative analysis, giving me a strong foundation in data collection and annotation processes. I am fluent in multiple languages, which enhances my ability to contribute to multilingual AI projects, and I thrive in collaborative, fast-paced environments where accuracy and clear communication are essential.
