About

I am an Engineering Manager specializing in Applied Machine Learning, Search, and Data Platforms, with extensive experience leading high-performing cross-functional tech teams. Currently at Mercari India, I am building and leading multiple teams focused on Search & Recommendations and AI-driven Trust & Safety, helping users find what they’re looking for more easily while ensuring a safer, more trustworthy marketplace. Previously at Mercari Inc. at Tokyo, I led a Machine Learning team responsible for improving product recommendations and strengthening the full ML lifecycle. At Rakuten Japan, I contributed to building a Feature Store within the Customer Data Platform and served as a technical lead for a blockchain-based data security initiative. Earlier at Yahoo! Japan, I worked as a Senior ML Engineer applying NLP and Deep Learning on Japanese text data for real-time search analytics, query classification, and recommendations. During my time at Yahoo! Japan, I had opportunities to collaborate on research projects which resulted in multiple patents https://scholar.google.com/citations?user=t5gZEZkAAAAJ&hl=en Apart from the core competencies, I am certified as a Six Sigma Black Belt and a Google Cloud Digital Leader, and I speak professional-level Japanese (JLPT N3). I am passionate about using data responsibly to build products that make people’s everyday lives better.
