I build production AI products that replace manual workflows, including AIRA at Optimal Virtual Employee—a real-time voice interview platform for City Home and GUS. I combined LiveKit WebRTC, Deepgram, ElevenLabs, Groq LLaMA, FastAPI, React, and MySQL to automate screening, proctor candidates, and generate five-dimension interview reports.

Previously at AGL-Hakuhodo, I built Generative AI chatbots, RAG pipelines across 50+ client files, and LangChain/LangGraph agents for retrieval and tool execution. My work improved SEO-team efficiency by 50%, increased information-extraction efficiency by 90%, and reduced client query response time by 60%.

I also develop machine-learning models, including regression and churn models using Scikit-learn and XGBoost, achieving 85–88% accuracy and precision. For a Japanese client, I built an Agentic HR Assistant with multi-tenant JWT access that improved HR operational efficiency by 70%.

I’m comfortable owning the full AI stack—from data pipelines, model layers, and RAG architecture to APIs, cloud deployment, CI/CD, and frontend integration. I’m driven by shipping scalable AI systems that solve real business problems.
