Senior🎓
Top SchoolMartin Olejar is a Senior Software Engineer based in Bratislava with 11 years of embedded and firmware experience spanning automotive sensors to high-performance CPU platforms. He has deep low-level expertise—ROM/UEFI/boot code, Linux kernel drivers, OpenBMC and QEMU customization—developed at Tachyum and NXP, and he led development of common MCU boot SDKs and test automation tools. His open-source contributions include adding Freescale KL43Z support to the widely used Arm Mbed OS (CMSIS/HAL, SPI/LPUART and USB device support), highlighting practical MCU bring-up skills. Martin pairs formal training toward a PhD in power electronics with hands-on schematic review, hardware testing and cross-team collaboration, often writing tooling in Python and Go to bridge HW/SW gaps. He’s known for taking ownership of the lowest system layers to accelerate platform readiness and verification.
