Ronin Dojo Design
One kernel.
Many brands.
Built to last.
A product studio that builds one durable software kernel and reshapes it into a portfolio of brands — so a school, a gym, or a niche business gets a real platform instead of a template.
How it works
Most studios rebuild the foundation for every client. We build it once.
- 01
Kernel
One shared technical substrate and a library of feature modules — leads, claims, payments, directories, scheduling. Built once, hardened in production, owned outright.
- 02
Brand
The kernel takes on an identity: your name, your voice, your colors, your language. Not a theme sitting on a template — a brand the software actually belongs to.
- 03
App
Your brand ships as its own product, on its own infrastructure and its own database. Any module can run on any app, so what one brand needs, the next one inherits.
The practical effect: you are not paying for a foundation to be invented again. You stand on one that has already been through production, and the work goes into what makes your business different.
Working together
Three ways in.
White-label
Take a finished platform and make it yours. The fastest route to real software under your own brand — you are not paying to invent what already works.
Custom build
Something the library does not cover yet. Built on the same kernel, so it arrives on a foundation that has already survived production instead of starting from nothing.
Care plan
Hosting, marketing, and continued work after launch. Software nobody tends stops being an asset — this is how it keeps earning.
Proof of craft
Shipped, not slideware.
Black Belt Legacy
LiveA verified Brazilian jiu-jitsu lineage platform — member profiles, rank verification, a technique library, payments. Built on the kernel, running in production, with real members.

More work is in build. Nothing appears here — no client name, no outcome, no quote — until that client has approved it.
Who builds it
A martial artist who became a systems architect.
I’m Brian. I train, and I build software — and the overlap is the point. The people who preserve a craft usually end up with software written by someone who has never practiced one.
The work draws on five things that rarely sit together: the martial arts themselves, web design and development, software engineering, SEO and marketing, and years as a senior developer and systems architect. One person carries a project from understanding the domain through the design, the architecture, the shipped product, and the marketing that sells it.
That is why the work is different. Nothing gets lost in a handoff, because there isn’t one.
Get in touch
Tell me what you’re trying to build.
The first conversation is a real one: what you do, where the friction is, and whether a platform is honestly the right answer. If it isn’t, I’ll say so.
