01About

I'm an electrical engineer who writes software for machines that have to work. Over the past eight years in Austria and Switzerland that has meant fieldbus slave stacks for industrial controllers, C++17 for mechanical ventilators in intensive care, and calibration sequences that drive precision instruments for high-voltage test systems.

The common thread is correctness under constraint: regulated lifecycles under IEC 62304, deterministic communication on real-time targets, and measurement chains where every number has to be traceable. I care about clean interfaces between hardware and software, tests that catch real failures, and documentation the next engineer is glad to find.

Away from the day job I take hardware ideas all the way through — schematic, layout, simulation, enclosure and bare-metal firmware — and photograph with Fotoclub Oerlikon.

THM-1 — battery e-paper climate meter

A pocket temperature and humidity meter designed end to end: schematic, two-layer board, 3D-printed enclosure and bare-metal firmware. The board, schematic and enclosure are generated from Python scripts (KiCad, CadQuery), so every revision is reproducible.

Circuit simulation in ngspice caught a real fault before manufacturing: switching on the display rail pulled the battery down to 1.3 V and reset the MCU on half-empty cells. Revision 1.1 adds a gate soft-start that keeps the dip under 0.11 V across all tolerance corners.
