Yuuma Sato

I am an AI Engineer specializing in designing and deploying intelligent systems that turn raw data into practical, production-ready solutions. My work focuses on Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), document intelligence, and end-to-end AI automation. I help startups and businesses build custom AI tools such as chatbots, knowledge assistants, data extraction pipelines, and domain-specific AI applications.

I have hands-on experience with model integration, prompt engineering, semantic chunking, vector databases, and scalable APIs. My approach emphasizes accuracy, reliability, and real-world usability—delivering AI systems that solve concrete business problems, not just demos.

If you need a focused AI engineer who can translate complex requirements into working AI products, I can help take your idea from concept to deployment.
