What I'm looking for

I’m interested in work involving artificial intelligence, large language models, online research, and emerging technologies, where I can contribute through evaluation work that improves model quality.

At Remotasks / Scale AI, I reviewed and annotated 15,000+ image, text, and audio items for machine learning training pipelines. I maintained 97–99% quality accuracy and applied client-specific labels and guidelines.

At Appen, I evaluated natural language outputs for fluency, factual accuracy, helpfulness, and rubric alignment, maintaining 94%+ inter-annotator agreement. I also provided written feedback on annotation guidelines, with several suggestions adopted into updated instructions.

As a freelance Virtual Data Entry and Research Assistant, I conducted web research, reviewed documents, and organized datasets in Excel and Google Sheets. I’m interested in artificial intelligence, large language models, online research, and emerging technologies.
