What I'm looking for

I seek roles where I can evaluate and improve AI models, design prompts and workflows, and apply my writing and technical skills in collaborative, impact-driven teams.

I began my career at OMRON Corporation working on image processing, factory automation, IoT, and robotics, where I coordinated international projects and prepared executive-level proposals that helped secure a major ¥2.5 billion contract.

Since 2023 I have worked as a freelancer building WordPress sites, writing books and articles about AI, and developing AI-powered applications such as a daily health-tracking tool and an AI-generated review posting app.

I specialize in prompt design, LLM evaluation, API integration, SEO writing, and workflow design, and I bring strong reading comprehension and hands-on experience with ChatGPT, image-generation models, and no-code/low-code development to improve model quality and training datasets.
