I am a northern light from Hamburg, today an Indie Builder and Solo Founder of Moinsen. I do not endlessly discuss problems — I build them and check what remains.

Autobiography

Not decorated. Documented.

The photos are not a gallery. They are markers: childhood in Schleswig, high school graduation, computer science in Kiel. The arc does not begin with AI, but with books.

Life Arc

From library kid to Indie Builder.

A northern German story in four hard cuts: seek knowledge, find technology, deliver internationally, build for yourself again.

Books were the first stack.

At four or five, alone to the library. Two, three kilometers to return with books. Only the form has changed: today they are called repos and papers.

The notice on the blackboard.

Three months without other applicants. Mainframes, Unix, real systems. No abstract career planning, but work that counts immediately.

A decade in a suitcase.

System software architecture between England, South Africa, Japan, Houston, St. Petersburg, Frankfurt and five years in Zurich.

No longer trading time for money.

Solo Founder, Agentic Coding, AI for Humans, own products. Eight parallel projects, 424 repositories, daily reality check.

Entry Points

Four ways through the site.

The homepage stays personal. Those who want to go deeper get clear doors: the long story, the built things, ongoing thoughts, and the work under Moinsen.

What is running right now.

No bio ends cleanly. Currently it is a product laboratory of Agentic Coding, trading, recipes, receipts, motorcycle travel and this website.

One idea, one repo. Reality check beats discussion.

The focus is not on a single big launch, but on fast validation: build, check, discard, sharpen.

In the middle of it, a new idea emerged: Memoirs-AI-Buddy.
Bonblick Receipt AI in MVP build-up.
Food Designer Managing recipes like code, in active development.
AI Trader Macro news trading system, validation since March.
Conductor Agentic Coding Stack v8.1.0 with 13 plugins, daily use.

Repetition is intentional.

The site may say these sentences more often. They are not claims, but operating system.

A man of his word.
Impossible is nothing.
Coding is my sport.
AI for humans, not for models.
