About me

I am an embedded software developer with a focus on test automation in Python and hardware-related programming in C/C++. In the last two years, I have developed automated regression tests and set up and managed hardware test systems at MAN Energy Solutions. Before that, I developed and commissioned control software for microcontrollers in C.

What sets me apart is the understanding of both sides, software and hardware. As a trained mechatronics technician and state-certified technician, I read circuit diagrams, set up test benches myself, and find errors even where the code alone doesn't help. This consistency from the circuit to the microcontroller to the cloud connection (MQTT, Docker, Grafana) is my greatest added value, especially in IoT and IIoT projects where hardware and software come together.

How I can support you:

Test automation in Python (regression tests, evaluation)

Embedded C/C++ development for microcontroller controls, including commissioning

IoT/IIoT connectivity for devices and machines (MQTT, Edge, Docker)

Software, system, and integration testing with clear documentation

I keep my skills up to date, most recently with further training in Embedded Linux, containerization (Docker/Kubernetes), and IT security (ISO 27001).

I am available immediately, remotely or on-site in the Ingolstadt / Augsburg / Munich area. I look forward to projects where I can combine hardware-related development and sophisticated test automation.
