Build, accelerate, learn.
13 years of product, mostly in teams. Today I run a team of agents and help founders and operators grow faster and better — not just with AI.
01How I work
How I work.
13 years of dev teams, QA, business owners — today most of my teammates are Claude agents. Same game: brief them, clear up questions, sign things off. 49 skills in use, a 14-agent job-application pipeline, Modal backends in production. This site itself came out of the setup. I help founders and operators grow faster and better — where AI gives leverage, where setup and people set the pace. I build the workshop, not just the prompt.
Build in public. Live on mfraunhofer.de, verifiable any time.
02What I'm working on
As of 23.04.2026
Six live projects. State live.
* I update this on no schedule, but often enough that nothing stale stays here. If a detail catches your eye: ask the bot or drop a line.
03Resources
Your AI setup can do more. Here's how to get it out.
Methods, workflows, and setups I use to ship software faster as a solo operator — from 2-minute tweaks to autonomous coding loops. Sorted easy to hard, in the order I learned them.
Learning path
Beginner
01
Set up a status bar for Claude Code.
5-hour and 7-day rate limits as a bar, reset countdown, session cost. So you don't slam into a token limit blind.
Intermediate
02
Set up Claude with Antigravity.
10 min setup, 20 min first project. Marry editor + Claude, build your first mini tools.
Pro
03
From problem to finished build plan.
Four small steps before the code loop: pitch, sharpen, PRD, tasks. With a bootstrap prompt to set it up yourself.
Pro
04
Run tasks autonomously with a review gate.
Geoffrey Huntley's Ralph loop, Matt Pocock's refinement, plus an automatic review pass before merge.
04Research
Research that helps you understand the present — and make better decisions.
Long pieces on topics that affect your work, your business, or your life directly. Sources are linked end-to-end — earnings calls, IEA reports, Bloomberg models — so you can judge for yourself.

67 bn.
Paper gains. Cash behind it: 1.5 bn.
The day Burry was right. Hypothetically.
Microsoft invests in OpenAI. OpenAI buys from Microsoft. Nvidia sells to all three. What quarterly reports call record earnings — and why Burry sees a pattern in it he's seen before.

TSMC share of leading-edge chips worldwide
The AI boom hangs on three companies. One of them sits in Oberkochen.
A region in Taiwan, a company in the Netherlands, an optics specialist in Baden-Württemberg. There is no plan B. What a stop would cost the world economy — and why the system holds anyway.

06Skills
46 custom Claude skills — the workshop.
What is a skill? A skill is a Claude building block: a set of instructions plus a few scripts that Claude pulls in on demand. Instead of explaining everything from scratch in every chat, Claude calls the right skill and works to a fixed pattern — like a routine you document once and use everywhere.
Live = in regular use. Beta = running, still being sharpened. WIP = internal, in progress.
