Akos Pasztor is a Team Lead Firmware Engineering based in Zurich with over a decade of hands-on experience designing and shipping embedded hardware and firmware across industrial, medical, automotive, and IoT products. He blends deep low-level C/C++ and RTOS expertise with analog/digital circuit design and PCB layout, having contributed to high-volume sensor modules and safety-conscious, MISRA-compliant firmware. At companies from Sensirion and Landis+Gyr to ETH Zurich, he shaped core architectures, improved CI/CD and test automation, and even modified Linux kernel drivers to boost SoC peripheral performance. An active open-source practitioner, he developed a customizable STM32 bootloader supporting SD/FAT32 firmware updates and SWO trace, reflecting a pragmatic focus on maintainability and field-upgradeability. Colleagues describe him as a technical leader who pairs rigorous engineering discipline with a knack for building tooling and infrastructure that accelerates teams.

Contributions summary:Akos was primarily involved in developing a customizable bootloader for STM32 microcontrollers. Their contributions focused on implementing core bootloader features, including flash memory operations (erasing, programming, verifying), and adding SD card support for firmware updates via a FAT32 file system. The user also added configuration options such as write protection and the setting of the vector table. Furthermore, they enhanced the bootloader with features for jumping to the system memory and support for SWO trace.
