13 Years of Hospitality × AI Engineering
Hotel work is about hospitality. But in reality, most of the staff's time was consumed by tasks — answering calls, transcribing reservation books, replying to emails, checking inventory.
For 13 years, I kept asking myself: "What if we could spend this time on the guests instead?"
Now I'm building that answer through technology. Because I know the frontline, I can build tools that actually get used. Because I understand the business, nothing I build is "delivered and forgotten".
Joined a hotel fresh out of university. Started my career at the front desk.
Took over occupancy, ADR, and RevPAR optimization. Learned to run a business through numbers.
Oversaw full hotel operations — people, finances, and service quality.
Started operating my own Japanese inn. Managed reservations, marketing, and guest relations single-handedly.
"Could AI handle all this manual work?" — I stepped into the world of technology.
Built MUSUBU — a LINE×AI reservation SaaS. A product built by someone who knows the pain firsthand.
Combining AI, tools, and systems to automate businesses. Not just writing code — conducting the whole operation.
Writing code is only part of the job. The real work is combining AI, tools, and people to design the optimal solution.
Tools built without frontline experience don't get used on the frontline. 13 years in operations is the foundation of everything I build.
Technology belongs behind the scenes. What the customer sees should always be human warmth. Automate everything backstage — relentlessly.
