Embedded C/C++ Entwickler / Software & Hardware Engineer - STM32, ESP32, AUTOSAR, KiCad, Altium

7/2025 – offen

Freelance embedded firmware and hardware development for microcontroller-based systems, IoT devices, battery-powered hardware, power electronics, BLE/RF boards, and prototype bring-up. I developed embedded C/C++ firmware for STM32, ESP32/ESP8266, and nRF-class platforms using STM32CubeIDE, CubeMX, HAL, FreeRTOS, Zephyr, peripheral drivers, interrupts, DMA, timers, UART, SPI, I2C, QSPI, SD/FatFS, and external memory interfaces. I also designed and reviewed PCB projects in KiCad and Altium Designer, including battery-management hardware, current/voltage sensing, BLE/RF layout constraints, production files, BOM, Gerber, CPL, and low-level hardware debugging.

7/2021 – 12/2024

Analysis and maintenance of an AUTOSAR-based HCP4 ECU project with multiple MCUs. I analyzed customer Problem Reports, identified duplicates, reproduced issues on test benches, built and debugged different ECU versions locally, validated fixes with testers, prepared analysis reports, and communicated with responsible development teams. Tools and topics included AUTOSAR Classic project structure, Vector CANoe, EB Tresos, winIDEA, in-circuit debugging, ECU runtime analysis, low-level debugging, issue reproduction and defect analysis.

2/2015 – 7/2021

Development and support of embedded Linux applications, backend services, and client applications for Comcast Xfinity products. I maintained and extended C/C++, Bash, Python, HTML and JavaScript components, supported Java-based backend services deployed on AWS and OpenStack VMs, worked with CI/CD updates, MySQL data processing, Yocto-based environments, GitHub, Jira and Confluence. The work included debugging, bug fixing, system scripting, device data collection, backend integration, customer-facing updates, code reviews and Scrum-based development.
