Creating the future of medicine with code
Anesthesiologist / Intensivist / Engineer
We read new papers in sepsis and anesthesiology every day and publish weekly and monthly editions in Japanese and English. Each new edition is posted to X automatically once a week.
Web app demos you can try, built on fictional data
A duty-roster system in actual use at Ogaki Municipal Hospital. It builds a month of night duties from day-off requests and duty rules, and shows which rule broke on which day when one cannot be kept.

A system that turns meeting recordings into minutes, in use for internal meetings at Ogaki Municipal Hospital. Two LLMs extract agenda items separately; quotes and numbers that are not in the transcript are dropped by rule before the results are merged. Everything runs on a local machine.

A practicing physician, from understanding the problem to shipping
As an intensivist, I have carried the everyday burdens myself: building duty rosters, writing meeting minutes, compiling reports. I listen to problems in the words of the people on the floor and build the solution together with them.
See my workI build AI tools such as Claude Code and Codex into design, implementation, and review, so you see working software at short intervals and can steer it. AI output goes through tests and a review by another AI, and I check the result myself.
Structured data, canonical URLs and multilingual settings, sitemaps, and day-to-day Search Console work. On this very site, I tracked down why pages had dropped out of search results and fixed it.
See the clinic website exampleMirube posts each new edition to X automatically once a week. For Instagram or LINE Official Account, I can look into an integration that fits your needs after checking each platform's official API and terms. Social posts by medical institutions fall under Japan's advertising rules, so a wording check can be built in before anything goes out.
Security headers, automated dependency updates with vulnerability checks, and secret scanning before publishing are part of the setup from day one. When personal data is involved, we design where it lives and who can access it together.
