What I'm looking for

I’m looking to contribute to fast-paced teams improving LLM quality through careful annotation, rubric design, and prompt engineering—while leveraging my linguistics and EN–ID translation skills to deliver accurate, high-quality outputs.

I’m a results-driven AI Data Annotation & LLM Evaluator with 1+ year of hands-on experience evaluating, labeling, and refining Large Language Model (LLM) outputs. Rooted in my English Education background in Linguistics and Translation, I design annotation rubrics and maintain data quality at scale—helping bridge human language nuance with measurable model performance.

Across freelance projects, I apply RLHF principles by ranking outputs and providing granular feedback, while flagging edge cases, ambiguous prompts, and failure patterns to guide refinement cycles. I also bring strong prompt engineering skills from hands-on experimentation, and I translate 1,000+ pages of literary and academic content to deliver precise bilingual Indonesian–English outputs.
