Hi, I'm

Christopher Schiefelbein

A dev in progress who teaches what they build: real apps, architecture decisions, and the process behind them.

I build web products with Astro, AI and real backend, and document the path so others can learn.

What I build

Real projects, in production. And an app that teaches you to think like an architect.

Flagship project

A PWA that teaches you to think like a software architect: how to choose and decide without tying yourself to a framework, language or tool. Universal criteria, curated progressive content — from 0 to 100.
