Freelancer Overview

I am an AI data annotation specialist with hands-on experience labeling over 4,000 samples across text, image, and audio datasets using industry-standard tools like CVAT and LabelImg. My background includes freelance annotation projects and product classification in a high-volume e-commerce environment, where I developed strong skills in guideline enforcement, quality control, and dataset preparation for machine learning pipelines. I am adept at handling tasks such as bounding box annotation, semantic segmentation, and text classification, and have contributed to computer vision projects like fine-grained bird classification using Swin Transformers. With a B.Sc. in Computer Science and solid Python fundamentals, I bring attention to detail, consistency, and a commitment to delivering high-quality training data for AI applications.
