Summary
🤩
RockstarAlex Borro is a senior embedded software engineer with 12+ years of hands-on experience across firmware, device drivers, and board bring-up for Linux, FreeRTOS and bare-metal systems. He has built real-time controllers for 3D printers at Ultimaker, contributed notable features to the widely used Marlin firmware, and driven electronics and motion-control projects for industrial CNC and automotive customers. Comfortable from low-level JTAG debugging to PCB design and system-level CI/CD, he blends deep C/C++/assembly expertise with model-based tools like Simulink and ETAS ASCET. His background spans high-assurance automotive development (MISRA-C) to rapid product iterations in additive manufacturing, and he’s implemented drivers for complex peripheral ecosystems (DMA, CAN, SPI, ADC, sensors). Dual Italian-Brazilian citizenship and a Mechatronics degree from Unicamp underpin a practical, international outlook and a persistent interest in electric mobility. Colleagues rely on him to close the loop between hardware validation and production-ready embedded software.
