Freelancer Overview

I have 2 years of experience of AI training and data annotation projects across various domains such as life sciences, general reasoning, and content evaluation. My work focuses on ensuring factual accuracy, linguistic clarity, and domain alignment in AI-generated responses. I have a background in biomedical science and bioinformatics, which allows me to bring subject-matter precision and analytical rigor to every labeling task, particularly in biology, healthcare, and technical writing domains. Beyond life sciences, I have also participated in LLM evaluation and rubric-based annotation projects, where I graded and refined model outputs according to clarity, tone, alignment guidelines and more.
