Freelancer Overview

I am an AI/ML operations professional with over 4 years of hands-on experience in data annotation, content moderation, and trust & safety workflows. My expertise includes training and evaluating LLMs on sensitive text, image, and video data, using tools like AWS Bedrock Playground and prompt engineering to ensure model safety and compliance. I have consistently delivered high productivity and quality in annotating and reviewing diverse content, including for major projects like Prime Video’s global trust & safety initiatives. My background also includes developing process improvements, such as automated work allocation and quality sampling systems, and collaborating across teams to uphold rigorous platform standards. I am skilled in policy enforcement, risk assessment, escalation management, and technical support, with a strong foundation in Excel, SQL, and SOP development.
