What is live.
What is moving next.

Each project names its state, my role and the proof that exists today. Private builds stay private without pretending the work is invisible.

03 / Range

One builder.
The whole product loop.

I'm a third-year Informatiker EFZ apprentice at CKW / Axpo, building reliable business applications while developing products of my own.

The breadth is deliberate: product judgment, application engineering and operating the systems all sharpen each other.
