English-Vietnamese Translator | Localization QA & NLP Annotation

I help global companies create Vietnamese content that sounds natural, trustworthy, and culturally accurate — not translated. I’m a native Vietnamese linguist with 8+ years of experience in English-Vietnamese translation, localization, linguistic QA, AI training, and NLP annotation. My work combines language accuracy, localization expertise, and reviewer-level quality control to help products and content succeed in the Vietnamese market. Many translations are technically correct but still feel unnatural to Vietnamese users. I focus on making sure your content reads fluently, preserves intent, and matches real user expectations across apps, websites, AI systems, and multilingual products. Over the years, I’ve worked with agencies, startups, AI companies, and global teams on projects involving SaaS localization, AI/LLM evaluation, translation QA, transcription review, and multilingual content workflows.
