What I'm looking for

I'm seeking remote contractor work in AI training, content evaluation, or related data projects, with availability for 20–40 hours per week.

At LinguaFlow Platform, I engineer and test Vietnamese and English prompts, compare LLM responses, and identify factual errors and subtle hallucinations. I also rewrite inaccurate or awkward answers into benchmark examples and explain my evaluations with evidence-based rationales.

In web-based fact-checking and knowledge curation projects, I verified claims against primary sources and organized datasets in Google Sheets, achieving a 99%+ quality and accuracy audit score. My work draws on Vietnamese language knowledge, English technical writing, and Information Technology studies at Industrial University of Ho Chi Minh City.
