Freelancer Overview

I have a strong background in data collection, cleaning, and analysis, with hands-on experience using Excel, SPSS, and Google Sheets to manage and organize datasets. My academic and project work have given me practical skills in preparing, annotating, and interpreting scientific and environmental data, including a research project where I collected, cleaned, and analyzed data on fish abundance using statistical methods such as correlation, regression, and PCA. I am detail-oriented, reliable, and adept at maintaining accurate records, making me well-suited for roles in data labeling and AI training data. My experience in laboratory and field environments has strengthened my ability to follow protocols, ensure data quality, and collaborate effectively within teams. I am eager to apply my technical and organizational skills to support high-quality data annotation and contribute to AI projects.
