Adding value.It’s in the name.
加, the first character of Katō, means to add. It’s also the job. I build next-level technology for businesses where getting it right is worth a great deal, and I only build things worth building.
This quarter so farsince 1 October
I only build amazing.
AI systems, data platforms, and the architecture underneath them. Products that run whole parts of a business, built by someone who has done it in banks, telcos and start-ups, and who will tell you straight when something isn’t worth building.
A chronic problem solver, with a career spent doing exactly that.
You can only build a skyscraper as high as its foundations allow.
So I focus on the foundations: the architecture, the framework and the data. You focus on the dream. Everything I build starts underneath, which is why it keeps going up.
Some of the things I’ve built
Only the work I can show in public. There’s a great deal more I can walk you through on a call.
Sentinel
A Mac companion for AI agents
One window for what an AI agent needs from you, what it's doing and in what order, what it has learned, and what it left running. It keeps the Mac inside a budget, and every check is broken on purpose to prove it works.
Roomi
Pitch the product, not the deck · getroomi.com
A platform for deploying working demos into a pitch room: the demo, the narrative and the materials behind a link per viewer, with analytics and feedback coming back.
Tengen
AI algorithmic trading, built data-first
A trading platform whose edge is connecting cause to effect as it happens: which event moved which price, and why. Underneath, a data foundation where every source, run and figure is recorded and can be traced.
The one you call when it has to work.
No account managers, no junior team, no hand-offs. One person who understands the whole thing, from the first conversation to the system running in production, with AI doing the heavy lifting and every decision made by someone who has paid for the lessons.

The app I run my own AI agents through: one window for what they need from you, what they’re doing, and what they’ve learned. Join my network and it’s yours.
