Freelancer Overview
I am a detail-oriented data annotation specialist with a strong background in computer science and hands-on experience supporting AI and machine learning projects. I have annotated over 5,000 images for computer vision tasks such as object detection and segmentation, and labeled text data for NLP applications like sentiment analysis and entity recognition, consistently achieving high accuracy. I am proficient with leading annotation tools including Label Studio, CVAT, Prodigy, and Amazon SageMaker Ground Truth, and have a working knowledge of Python for basic scripting and workflow automation. My experience collaborating with remote teams, refining annotation guidelines, and ensuring data quality has developed my analytical, problem-solving, and communication skills. I am passionate about contributing to innovative AI solutions by delivering reliable, high-quality training data.
