Freelancer Overview

I am a detail-oriented AI Training Specialist with 3 years of hands-on experience in data labeling, annotation, and quality assurance across video, image, audio, and text datasets. My expertise includes applying complex annotation guidelines, performing both fine-grained and coarse segmentation for computer vision projects, and conducting audio transcription with precise timestamp labeling. I have consistently maintained high accuracy standards, achieving a 95%+ quality score on multiple projects by carefully validating AI model outputs and identifying labeling errors or hallucinations. Skilled in using tools like Labelbox, Scale AI, CVAT, SuperAnnotate, and Amazon SageMaker, I excel at structured data management and remote collaboration, ensuring that datasets are accurate, consistent, and ready for AI model training.
