I build things that
connect to the real world.

Started with a soldering iron.
Never really stopped.

I grew up building radios, antennas, and circuits. CB radio as a teenager, then amateur radio — shortwave, mediumwave, UHF, VHF. Decoding RTTY weather fax data from shortwave transmissions. Building antennas from scratch.

Then the internet arrived, and I was hooked. At 24, I founded mp3.de — Europe's largest music portal at its peak. Millions of users, seven-figure revenue, exit in 2002. After that, consulting for enterprises led me to Deutsche Postbank / Deutsche Bank, where I spent a decade building online banking platforms for millions of daily users.

Today I run workingbits, building SaaS products, ERP systems, and AI-driven development workflows. I work with autonomous AI agent teams that write, test, and review code in parallel — turning what used to take sprints into hours.

The best products are built by people who understand the full picture — not just the code, but the hardware it runs on, the business it serves, and the users who depend on it.

The thread that connects it all: I build things that work in the real world. Whether it's firmware on a microcontroller, a cloud backend handling thousands of IoT devices, or a mobile app — I care about the full stack, from the solder joint to the user interface.

AI-driven development is
not about generating code.

It's about everything around it. I build autonomous AI agent teams that architect, implement, test, and review — in parallel.

A browser agent navigates the entire app, tests 300 use cases, takes screenshots, creates a video with voice-over. Two minutes — and you know exactly what works and what doesn't. QA reimagined.

Off the grid, off the road,
out of the comfort zone.

I travel to places where the road ends and the navigation gets interesting. Iceland's uninhabited highlands — multiple times, sometimes with my daughter. The American Southwest. Southeast Asia. Always drawn to terrain that demands self-reliance: no cell service, no rescue nearby, no plan B except the one you bring.

One highlight: crossing the Sprengisandur, Europe's largest stone desert. Days without civilization, glacial river crossings with unknown depth, carrying everything — fuel, water, food, spare parts. The kind of trip where breaking down isn't an inconvenience, it's a situation.

My tool for these trips: a Jeep Wrangler Rubicon, bought stock and built up myself. 3.5-inch lift, 35-inch tires, axle breathers relocated to roof height for a full meter of wading depth, winch on the front, and an AluCab rooftop tent on top. For Iceland, the Jeep gets shipped on a freight ferry from the container port in Rotterdam, Netherlands — drive it there, load it, fly to Reykjavík, pick it up at the harbor. Not a show car — a machine built to get somewhere and sleep when you arrive.

Iceland is also where I ride. Icelandic horses have a unique fifth gait — the tölt, a smooth, fast ambling pace that lets you cover rough terrain without the impact of a trot. Interestingly, some horse breeds in Latin America share a similar extra gait — the Paso Fino's fino and the Peruvian Paso's paso llano. A fascinating parallel between two regions I'm drawn to.

Most of the aerial shots you see here are mine — I fly DJI drones wherever I go. Mavic, Air, Mini — there's always one in the bag. Hard to resist when the landscape looks like another planet.

When I'm not in the dirt or in the air, I'm usually under a hood. Classic sports cars, old Porsches, anything mechanical that has a story. Different kind of machines, same fascination.
