01 · The demo

Anyone can build you a demo that works.

Two afternoons and an API is enough to show something that answers well in front of a committee.

02 · The gap

Production is another matter, and the AI is not what holds it up.

It is access permissions, deciding which version of each document is the right one, and data that cannot leave your network.

03 · The proof

An AI system does not break: it keeps answering, only worse.

Which is why trying it for a while proves nothing. You measure it with a case suite that protects every change that comes after.

04 · That is my job

I take generative AI from demo to production.

With auditing and security included. And if your case does not need AI, I say so before charging you for it.

This website is a working demo.

The assistant below is not a form in disguise. An open model answers it, running on my own GPU, with the same guardrails I build for a client: it invents no prices, admits what it does not know, and if it goes down it says so instead of breaking.

What could be built in your case?

Five questions and my own model tells you what it would build, where it would start and what it would not do. If your problem is not solved by AI, it says that too.

// real cases

This is not theory. It is in production.

Where being wrong is expensive: health data and legal files, with human review and GDPR compliance.

// how I work

Three steps.

Fixed-price projects or monthly dedication, always with reviewable deliveries.

01

An honest diagnosis

I look at your case and tell you what I would do, how long it would take and what the risks are. If you do not need AI to solve it, I tell you that too.

02

Building in deliveries

Working pieces from the first week, not promises. You see and validate every step on your own case.

03

Production and guarantees

Deployment, a test suite that protects every change, security and documentation so your team can maintain it.

Got an AI project on your hands?

Tell me what you want to build, or what isn't working. I'll reply with an honest assessment: what I would do, how long it would take, and whether you actually need AI to solve it.
