Data and ML platforms · Production, not demos

Beyond the vibe.

Hi, I am Johannes.

Anyone can vibe-code a demo in an afternoon. Getting it into production, on real data with real users, is a different animal. That part is what I do. No slide decks. Commits.

What I offer

What a demo leaves out.

The three parts that turn a demo into a product. I build all three.

01 / Data

Real data, not samples

Pipelines, storage, serving. Sized for everything you have, not for the sample in the demo.

02 / Feature

Pilot to production

The edge cases, the error handling, the last features the demo left out.

03 / Operations

Boring on purpose

Monitoring, cost per request, reliability. The part demos skip, and the reason it is still up in a year.

What I built, what broke, and what I learned.

Works in the demo, nowhere else?

Twenty-five minutes. I want to understand where it is stuck before I propose anything.
