What I'm looking for

I’m looking to lead and improve multimodal dataset quality—reviewing labels and evaluating AI responses for accuracy, relevance, and guideline adherence—while training teams and refining annotation workflows in fast-paced environments.

I’m an AI data annotation and evaluation specialist focused on multimodal quality assurance and in-depth language evaluation. I review labels for guideline adherence, assess accuracy, and handle complex tasks by flagging edge cases and ambiguous labels.

As an AI Dataset Data Annotation Team Lead, I led QA for annotated datasets, trained and supported annotators, and resolved quality issues to maintain high-quality ground truth data. I’ve also worked as a Data Reviewer and contributed as a freelance contributor to multimodal annotation and AI response evaluation projects, adapting to evolving review standards and remote workflows.
