I answer why before we get lost in the how — then build the right thing.

What I build.
Web apps in production
What runs behind the design: backend, data model, deployment.AI automation
Instead of the manual step that eats time — and the systems that refuse to talk to each other without an integration.Embedded & sensors
Sensor to dashboard, firmware included.Event-management PWA, built and shipped solo.
MCP server that opens Austrian federal law to LLMs.
Control software for an industrial printhead-cleaning rig.
Office air quality, from sensor firmware to the dashboard.
What comes out when an idea gets built all the way, with nothing in the way.
How this works.
Discovery sprint
Maximum 1 week, fixed price. I dig into the problem and hand back a written scope, an architecture, and an honest estimate. No commitment past it.
Ongoing build
Reachable and iterative — considered, not just executed.
Fixed-scope build
A defined thing, a defined price. Best when the need is already clear.
Engineer by training.
Builder by instinct.
Engineering first, economics alongside it. That combination exists because the most brilliant engineering on the wrong thing is waste.
