Freelancer Overview

I am an experienced data annotator and AI data trainer with a strong background in creating and refining high-quality training data for large language models. My work includes developing and testing LLM prompts, annotating multimodal outputs (text, video, speech, and image), and ensuring accuracy and consistency in large-scale annotation projects. I have a solid foundation in economic analysis and data analytics, with advanced skills in Microsoft Excel, Power BI, and SQL, gained through roles in both government and private sectors. My entrepreneurial experience has strengthened my project management, team leadership, and quality control abilities, allowing me to contribute fresh perspectives and maintain high standards in AI data workflows. I am passionate about leveraging my analytical skills and attention to detail to improve the reliability and performance of AI systems.
