Sensors first.
Then the model.

I get honest data out of machines, then write the software that reads it. CO₂ electrolysis test benches at Fraunhofer. Car infotainment computers at HARMAN. Small devices that shipped and are still running.

What I am building now

A live dashboard for a CO₂ electrolysis rig

Scientists at Fraunhofer were running experiments on a test stand, then working the results out in Excel hours later. I asked if I could fix that. It became my master's thesis.

The real thing, running. Six tabs of live readings off the rig.

123 open warranty cases at HARMAN, taken into single digits in six months
5 min to get a test campaign ready at Fraunhofer, down from hours
9 engineering projects, two of them sold to customers
4 peer-reviewed publications, one of them in a Scopus journal

How I work

Data is useless if you cannot get it out of the machine cleanly.

01

Get the signal out

Most data problems turn out to be hardware problems in disguise. A noisy bus, a late interrupt, a clock that resets when the power drops.

02

Clean it where it is measured

Fix broken rows, line every sensor up in time, put it somewhere you can ask questions of. A run should be ready to read in minutes.

03

Then let the model speak

Spot the moment the behaviour changes. Forecast against what the machine did before. This works because the input was trustworthy.


Selected projects

Things that had to work outside a notebook

Nine projects, most of them on video.

Two were sold to customers. Two are published. All of them had to survive contact with real hardware.
