Talk at Svelte Society Berlin, Sep 2, 2026. The slides, spec-driven and agent-built like the project they describe.

Specced, not vibed.
I work out what a system should do and why, then build it with AI in the loop.

How I build
There are no vibes in a spec.
Every project runs through the same chain. Each step leaves an artifact in the repo, and the agents only build once the spec stands.

- PRD
- Architecture
- ADRs
- UX
- Epics
- Stories
- Agent builds
- CI
- Review
- Prod
Slow. Expensive. Worth it.
About
People say they get inspired. I get obsessed.
A new interest means hours of research and a knowledge base for everything. Sometimes it ends in a project:
- 2006 Kontempora Online print gallery for young photographers. Before Instagram existed.
- 2019 D'IGGY High-efficiency tick repellent. Named after the dog.
- 2025 Stimmungsschau Party sentiment analysis of German TV news.
- 2026 mmcp Multi-tenant memory engine for AI agents. Total tenants: one.
I'm really good at having ideas. Not so good at running them. Some are different.
Around twenty years in the digital stack: strategy, architecture, project lead, earlier also code. Hands-on with LLMs since ChatGPT in late 2022. I work as Head of Platform & AI at mtc.berlin.
