Freelancer Overview

I am an experienced data annotation specialist and AI trainer with a strong background in labeling and evaluating text, image, and audio data for projects in robotics, large language models, LTD mapping, and 3D Lidar. My work includes high-quality annotations, voice recordings for virtual assistants and TTS applications, and detailed feedback to support model training. I am skilled in using tools such as Audacity for audio data, and have hands-on experience as a Scale AI task reviewer and voice actor. My attention to detail, consistency, and ability to adapt across domains allow me to deliver precise, reliable training data for AI development. I thrive in remote, collaborative environments and am committed to ensuring data quality and accuracy in every project I undertake.
