zawatronics — Embedded Systems Development

// Services

What I do

Circuit design, PCB layout and prototyping — tailored solutions for your use case.

C/C++ development for microcontrollers, RTOS and IoT connectivity.

Connecting sensors, actuators and the cloud into working end-to-end systems.

Enclosure design, 3D printing and functional prototypes — mechanics that match the electronics.

// About

I'm Maximilian Zawadzki — an embedded engineer based in Saarbrücken.

Mechatronics apprenticeship
B.Sc. in Mechatronics and Sensor Technology
Several years as an embedded engineer in industry — sensors, instrumentation, prototyping
Focus areas: sensors, instrumentation, automation, the hardware/software boundary
Open to new topics and unusual problem statements

→ Also registered as an electrical contractor (HWK Saarland) — if you need engineering and installation from one source.
