Freelancer Overview

I have experience working with data labeling and AI training workflows through hands-on projects in machine learning and NLP. In my toxic comment classification project, I worked extensively on preparing and cleaning text data, handling class imbalance, and ensuring high-quality labeled datasets for model training. This included tasks like preprocessing noisy user-generated content, validating labels, and structuring datasets for supervised learning. I also gained exposure to evaluation processes by comparing multiple models and analyzing performance metrics such as precision, recall, and F1-score, which are critical in assessing label quality and model reliability. Additionally, I have experience building data pipelines and working with large-scale datasets using Python, SQL, and AWS tools like Glue and Athena. In my NYC Taxi Demand Prediction project, I engineered features, validated data consistency, and ensured data quality before training models like LightGBM. My background in data engineering and analytics, combined with an understanding of machine learning workflows, allows me to contribute effectively to AI training tasks that require attention to detail, structured thinking, and high-quality data annotation.
