Freelancer Overview

I am a detail‑oriented contributor with hands‑on experience in data annotation, AI evaluation, and digital product testing. My background includes labeling text and image datasets, applying structured guidelines, and ensuring consistency across large volumes of training data. I am skilled at identifying hallucinations, logical errors, and factual inaccuracies in AI outputs, and providing clear, structured feedback to improve model performance. In addition to annotation, I bring strong technical comfort with evaluation dashboards, browser‑based testing tools, and collaborative platforms such as Google Workspace and Trello. My ability to follow rubrics, maintain accuracy, and communicate findings clearly makes me well‑suited for remote freelance projects in AI training and evaluation.
