Freelancer Overview

I am an experienced data annotator and AI training data specialist with a strong background in audio, video, and text annotation for machine learning applications. My work includes reviewing and labeling dashcam footage to enhance AI safety models, recording and annotating multilingual voice data for speech systems, and performing quality assurance on audiobook narration alignment and speech-to-text transcripts. I am skilled in using a variety of annotation and project management tools such as Labelbox, Jira, Notion, Google Workspace, and more. My experience spans domains like computer vision, NLP, and robotics, where I have generated, validated, and reviewed datasets with a focus on accuracy and compliance with annotation guidelines. I thrive in collaborative environments, working closely with R&D and product teams to improve AI outputs, and bring a creative, detail-oriented approach to every project.
