Freelancer Overview

I have hands-on experience in AI data annotation, where I specialize in labeling and organizing diverse datasets for machine learning, including text, images, and audio. My role at Outlier.ai involves ensuring data quality by accurately categorizing information, transforming unstructured data into structured formats, and verifying compliance with project guidelines. This work has strengthened my ability to detect errors, avoid bias in datasets, and contribute to improving model accuracy through iterative feedback and refinement. Beyond data labeling, my background in customer service, translation, and administration across multilingual and cross-cultural settings enhances my precision, adaptability, and communication skills. Fluent in English, native speaker of Bahasa Indonesia, and Japanese, I bring strong attention to detail, problem-solving capabilities, and a results-driven mindset; qualities that allow me to excel in fast-paced AI training data projects and ensure reliable, high-quality outcomes.
