I’m an AI Evaluator and game tester who reviews LLM outputs and gameplay quality with structured, actionable feedback.
What I'm looking for
I’m a detail-oriented AI Evaluator and game tester focused on evaluating AI-generated content across gaming, data annotation, and human-machine interaction. I bring strong analytical thinking and written communication, with a background in fact-checking, tone evaluation, and structured feedback delivery.
In freelance playtesting, I run structured sessions across mobile and PC titles, identifying bugs, UX issues, and inconsistencies in gameplay flow. I deliver detailed written reports on mechanics, balance, and player experience, and I’ve evaluated gaming terminology, cultural accuracy, and tone consistency in AI-assisted game content.
I also work as a UX tester using think-aloud usability testing for web and app products. I assess content clarity, tone accuracy, and factual correctness of digital interfaces while maintaining high ratings through careful, easy-to-act-on feedback.
As a Data Annotator, I annotate and review AI training datasets (text, image, and audio) and evaluate model outputs for accuracy, hallucination, relevance, and alignment. Using detailed rubrics, I rate responses for factual correctness, completeness, and safety, and I’ve supported voice data collection projects as a volunteer contributor.
