Freelancer Overview

I have over five years of experience working with data through programming, preprocessing, and machine learning workflows. My background includes hands-on data annotation and freelance labeling work, where I’ve contributed to projects that require high attention to detail, consistency, and clear understanding of data quality standards. I’m experienced in building and cleaning datasets, evaluating model outputs, and applying structured guidelines to ensure reliable annotations across different data types. I also have strong technical skills in Python and applied ML, which allow me to approach labeling and evaluation with a deeper understanding of how training data impacts model performance. My experience spans data preprocessing, feature engineering, model testing, and error analysis—skills that complement and elevate my work in AI training and evaluation. I bring a mix of analytical thinking, technical proficiency, and careful judgment, making me well-suited for roles involving data labeling, AI training, content evaluation, or model-quality assessment.
