Embedded Systems Development

Software.
Close to
the hardware.

I develop software and hardware for devices that measure, control and regulate. From the first circuit to testing on real hardware.

04 / About me

Hannes Pauli
Diplom-Informatiker · Kürten

Systems thinking.
Attention to detail.

I have developed embedded systems since 2008 and worked freelance since 2022. I connect firmware, electronics and testing, from the first measurement signal to the finished device.

Primarily remote, with on-site work by arrangement.
