Cao Tien Dung

I am an AI Operations and Evaluation Specialist with over 2 years of hands-on experience in machine learning pipelines, LLM benchmarking, and dataset quality control. Working remotely with international teams at DataAnnotation, I have specialized in evaluating complex model outputs, crafting prompt rubrics, and conducting rigorous quality assurance across both text and audio domains. During my recent projects, I successfully evaluated and validated thousands of AI data samples, consistently maintaining an accuracy benchmark of over 98% against rigorous rubrics. Additionally, I helped optimize review workflows, reducing task turnaround times by 25% while maintaining zero tolerance for guideline deviations. I am looking for a full-time or contract remote role as an AI Engineer, Prompt Specialist, or AI Operations Engineer where I can contribute to building and refining state-of-the-art models. I thrive in asynchronous, documentation-first teams and have a strong self-driven work ethic.
