Freelancer Overview

I am a detail-oriented data annotation specialist with over three years of experience supporting AI and machine learning projects through high-quality labeling, tagging, and validation of image, text, and audio datasets. My expertise spans domains such as autonomous vehicles, healthcare, and customer support, where I have consistently delivered precise annotations using tools like Labelbox, CVAT, SuperAnnotate, and Amazon SageMaker Ground Truth. I am skilled in NLP tasks including intent classification, entity tagging, and sentiment analysis, and have a strong background in QA review, ontology structuring, and data compliance (HIPAA, GDPR). My experience includes working on federal datasets requiring accuracy and confidentiality, developing annotation guidelines, and collaborating remotely across diverse teams. With a foundation in psychology, I bring a keen understanding of human behavior to annotation workflows, ensuring both quality and relevance in training data.

Labeling Experience

Data Annotation Specialist

Scale AIImageSegmentation

As a Data Annotation Specialist at Scale AI, I labeled large volumes of image, text, and audio data for autonomous vehicle, healthcare, and NLP projects.
