Freelancer Overview

I am an experienced AI trainer and data annotator with a strong background in labeling and validating diverse datasets, including images, text, and video, for machine learning model training. My expertise covers a wide range of annotation tasks such as image annotation, semantic segmentation, named entity recognition, and sentiment analysis. I am highly proficient in using industry-standard annotation tools like CVAT, LabelImg, Supervisely, Prodigy, Amazon SageMaker Ground Truth, and the Scale AI platform. With a proven track record of maintaining a 98% accuracy rate across multiple projects, I have also created taxonomies, developed annotation guidelines, and trained junior annotators to ensure data quality and consistency. My technical skills include Python, SQL, and basic web development, and I am committed to delivering reliable, high-quality training data for AI systems.
