What I'm looking for

I'm looking to apply Japanese-Thai multilingual judgment, adversarial evaluation, and evidence-based documentation to generative AI safety and Trust & Safety work.

At Hitachi Digital Services, I evaluate generative AI models against Trust & Safety standards, designing adversarial prompts and multilingual test cases for Japanese-language and safety-critical scenarios.

I apply structured guidelines to assess prompts, conversations, and model responses, identifying safety-evasion techniques, escalation patterns, and policy-relevant edge cases. I document clear, evidence-based findings for engineering and policy review.

Previously, I built data-driven collection strategies, dashboards, workflows, and departmental plans at Orico Auto Leasing and Promise Thailand. As a native Thai speaker with JLPT N1 Japanese, I bring cross-cultural judgment, translation, interpretation, and operational improvement experience.
