I build at the speed of a team.
I wrote my own AI-driven development framework. It runs on every one of my products, and it is what explains the rest of this page.

FatThumb
The six addresses are live and checkable: klaas.pro, studio.klaas.pro, fatthumb.klaas.pro, edit.klaas.pro, noqen.com, soleo.group. The other numbers come from the repositories themselves.
What I have built.
Four ways to work together.
Ship a product from zero
From the business need to deployment. The web, the native mobile app and the models, by the same person, with no seams between three vendors.
Take over a platform
An existing system to hold, stabilise and move forward, without rewriting it from scratch because the code is unfamiliar.
Industrialise a model
Model orchestration in production: cost per call, latency, retries on failure, and a reproducible result.
Speed up a team
Install the chain I use myself: framing, anchoring before the code, automated review, verified deployment. And leave it behind me.
