What I'm looking for

I’m looking for a role training Japanese-language LLMs through evaluation, annotation, and refinement to improve accuracy and fluency, while collaborating remotely with cross-functional teams to meet quality benchmarks.

I’m a detail-oriented AI Trainer and Language Specialist with over 3 years of experience training and tutoring AI models across multiple organizations, including projects for Google Gemini. As a native Japanese speaker with a strong command of written language, I apply my background in writing and linguistics to deliver high-quality Japanese-language AI training data.

In my current role, I provide expert Japanese-language AI training for large language models by evaluating, annotating, and refining AI-generated Japanese text to meet high linguistic and contextual standards. I focus on nuanced language error detection, cultural accuracy, quality assurance, and remote collaboration with cross-functional teams to meet project deadlines and benchmarks.
