I'm Hiroyuki Ota, a software engineer and engineering manager based in Tokyo. I build AI agents, data platforms, and the engineering teams behind them.

What I can help with
- AI agents and AI adoption — e.g. an LLM-powered agent for searching internal company data
- High-performance services, end to end — e.g. an ad platform serving 1,000 QPS within 100 ms
- Data platforms and data use — e.g. order automation for 800 retail stores processing 70M records a day
- Building engineering organizations — grew an org from 0 to 40 through hiring and culture; managed 20 engineers over four years
