The Story
Born in Japan, raised in the U.S. I've lived across Spain, Estonia, and beyond. This global perspective shapes everything I build.
After studying Environmental Engineering at Brown, I discovered my real passion: making powerful tools accessible to everyone.
I believe AI should be humanity's great equalizer: the tutors, advisors, and assistants once reserved for the privileged few should be available to all.
"AI as the glider for everyone's mind."
AI Consulting
From strategy to implementation. I help teams build AI that actually works.
AI Strategy
Identify high-impact AI opportunities in your business. Cut through the hype and focus on what moves the needle.
Custom AI Tools
Prototype-to-production AI workflows. Chatbots, automation pipelines, and internal tools built fast.
Team Training
Upskill your team on AI best practices. Hands-on workshops, not PowerPoint marathons.
Tools & Experiments
One-off utilities and side projects I've built. Feel free to use them.
ICS Validator & Fixer
Paste or upload any .ics calendar file. Auto-fixes missing timezones, UIDs, line folding, and other issues. Includes a weekly calendar preview with timezone conversion.
VCF File Splitter
Upload a .vcf file with multiple contacts and split it into individual vCard files. Download as a ZIP for easy iPhone/Android import.
Frequently Asked Questions
Questions I get asked more than I'd like.
No. But I do worry about how it will either force us to sharpen our critical thinking or make us complacent. In many ways, it's like Up or Brave New World. The question isn't whether AI will control us, but whether we'll choose comfort over growth.
No, Japan is not a perfect country without flaws. And yes, I watch anime. Cowboy Bebop and Paprika are masterpieces. I will die on this hill.
Tea. Green tea specifically. And I'm willing to change your mind on this; most green tea in the US is awful (cough cough Lipton). Try the real stuff and we'll talk.
Yes. My advisor once said, "Now that you have a degree, I'm honestly surprised you became an engineer." I also did conservation work in Maui helping maintain Waikamoi Preserve (one of the wettest places in the world). Somehow it stayed that way even with my dry humor.
- I can snap on any surface. Tables, walls, my own face. It's a gift.
- I beat Total War: Shogun 2 on Legendary as the Tsu faction (the independent republic). If you know, you know.
- I send postcards to friends around the world. DM me your address, I'm serious.
- My dream is to make enough friends globally that I always have a couch to crash on.
- I can only count to three the German way. My hands physically refuse to do it any other way.
I grew up in the US of A. I don't have a sense of humour. Please don't sue me.
Cowboy Bebop and Paprika are masterpieces, no debate. Also, if you're anywhere from your late teens through your early thirties, you absolutely must read The Brothers Karamazov. It will change how you see the world.
