What I'm looking for

I’m looking for a role where I can evaluate LLM responses and annotate/validate datasets, doing high-accuracy QA and fact checks under clear guidelines—while collaborating with ML teams that value speed, attention to detail, and consistent quality.

I’m an AI Data Annotation and Evaluation Specialist with 4+ years supporting machine learning and generative AI projects. I focus on AI response evaluation, dataset annotation, and validation to help teams trust the outputs they ship.

Across my freelance work, I evaluate AI-generated responses for quality, accuracy, relevance, and guideline compliance. I annotate and validate datasets, run quality assurance reviews, and perform fact verification while meeting strict project deadlines.

I’m known for accuracy, attention to detail, and working independently. I’m also a quick learner who adapts to new tools and guidelines, ensuring consistent, high-quality results from start to finish.
