So I Built My Own Software."},"content":{"rendered":"\n

20 years ago, I was an ASP developer. I could build anything with it.<\/p>\n\n\n\n

Then the world moved on. My favorite stack became “legacy”. For a while, I thought my time as a developer was over.<\/p>\n\n\n\n

Two years ago, I moved to Osaka and started a small vacation rental business. I loved hosting guests from all over the world, but I hated the daily operations. Answering the same guest messages at 2 AM. Scheduling cleaners. Updating prices manually on 3 platforms. Changing the same listing description in 3 languages.<\/p>\n\n\n\n

I looked for software to help. They were either too expensive, too complicated, or didn’t understand how business is actually done in Japan.<\/p>\n\n\n\n

So I did what an old programmer does. I opened my laptop.<\/p>\n\n\n\n

I started building small tools with Python. First a script to auto-reply to guests. Then a cleaner scheduler. Then a pricing bot.<\/p>\n\n\n\n

With AI, everything became 10x faster. What used to take me a month in the ASP days, now takes a weekend. Python + FastAPI + Next.js + AI – this is my new stack.<\/p>\n\n\n\n

This website is my new workshop.<\/p>\n\n\n\n

I will share everything I build here in the open:
How I automate my Airbnb<\/a> business, the small tools I make for hosts in Japan, and what I learn re-learning how to code in the age of AI.<\/p>\n\n\n\n

This is not a tutorial blog from an expert. It’s a logbook from a builder.<\/p>\n\n\n\n

If you are also a host, a solo founder, or an old programmer trying to come back, welcome. Let’s build something useful.<\/p>\n\n\n\n

\n\n\n\n

P.S. I\u2019m currently building a micro-SaaS for Airbnb hosts in Japan. If you run rentals in Osaka, I\u2019d love to chat.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
