Bounding Box

Freelancer Overview

I am a detail-oriented data annotator and AI training specialist with hands-on experience in image and text annotation, quality rating, and model evaluation. My work spans computer vision projects—such as bounding box annotation for e-commerce product images—and NLP tasks like sentiment and topic tagging for news data. I consistently deliver high-quality, guideline-compliant labels, with a strong focus on accuracy, edge-case judgment, and self-auditing to ensure data integrity. My freelance background includes microtask platforms where I maintain a 98%+ accuracy rate and high client satisfaction. I am skilled at clarifying complex instructions, producing QA reports, and collaborating to improve annotation processes for better model performance.
