Freelancer Overview

I am a detail-oriented data annotator with over 4 years of experience providing high-quality labeled data for AI and machine learning projects. My background includes working with a variety of data types—text, image, video, audio, and LiDAR—using advanced tools such as Labelbox and techniques like bounding boxes, polygons, and semantic segmentation. I consistently maintain accuracy rates above 98% through rigorous quality assurance and careful documentation of best practices. My experience spans collaborating with cross-functional teams to refine annotation guidelines, optimize workflows, and deliver actionable insights that improve model performance. I am comfortable working under tight deadlines, adapting to new domains, and ensuring data integrity for computer vision and NLP projects.
