Freelancer Overview

I have over three years of experience as an AI Trainer, working as an independent contractor on diverse data labeling and training data projects. My work includes annotating images using bounding boxes, generating high-quality prompts for large language models (LLMs), and designing evaluation rubrics to assess AI responses. I’ve consistently handled multiple projects across different domains, demonstrating strong adaptability and the ability to quickly understand and apply complex annotation guidelines while maintaining accuracy and consistency. What sets me apart is my combination of technical annotation expertise and strong critical thinking skills, allowing me to identify edge cases and improve data quality. I bring a detail-oriented approach, creativity in prompt generation, and a proven ability to manage tasks efficiently under tight deadlines. My background in business and team leadership also strengthens my communication, organization, and problem-solving abilities, making me a reliable contributor to high-quality AI training workflows.
