Consulting

I work as an external consultant, architect, or developer — embedded in your team or as an independent project lead. The role adapts to what your project needs.


How I Work

I use AI-powered development tools like Claude Code as a core part of my workflow — and use them productively to build my own products (The Taurus, neurg.de). At the same time, I can debug any problem down to the Linux configuration when necessary. 15 years of experience across the full stack means: I understand what’s happening under the hood — even when modern tools accelerate most of the work.


Services

Software Architecture & Consulting

Technology decisions, system design, modernization of existing architectures. I bring order to grown systems and help teams strategically reduce technical debt.

Full-Stack Development

From a single React component to complete system architecture. Frontend, backend, ML — as needed.

Technical Leadership

First leadership role at 25 — since then regularly in tech lead and architect roles. I help teams get better.
