Yolanda Adet Pratiwi

I’m a detail-oriented Data Annotator focused on improving ML and Large Language Model (LLM) performance through high-quality data labeling, content evaluation, and quality assurance.

As a freelance annotator, I annotate text, image, audio, and conversational data, ensuring accuracy and consistency while strictly following annotation guidelines, quality standards, and project deadlines.

I also evaluate AI and LLM-generated responses—rating for accuracy, relevance, and safety, identifying errors, and providing clear quality feedback to support model training and improvement.

When needed, I work on AI transcription by converting audio into accurate text, reviewing and correcting AI-generated transcripts, and ensuring proper grammar, punctuation, and formatting to maintain consistently high quality.
