Message

At Daimler Truck, I developed secure boot and OTA firmware update concepts for Infineon AURIX TriCore and dual-core ARM Cortex-M33 systems. I also helped achieve cybersecurity management and software development compliance with ISO 21434 and UN R-155/156.

At Hilti - Power Tools, I designed and implemented a scalable IoT security solution using ASCON, AES, and ECDSA. I reduced firmware delivery time by 70% with a CI/CD generation pipeline and improved secure boot time by 55% on an ARM Cortex-M4 MCU.

At Alten, I developed AUTOSAR Classic basic software modules for Infineon Cortex-M3 microcontrollers. I coordinated 20 engineers across the EU on MISRA- and HIS-compliant software and automated static-analysis tool configuration, reducing setup time by 80%.

Earlier, at Automotive Centre of Technology Galice, I developed FreeRTOS schedulers and bare-metal C modules for real-time control systems. I began at Intec Motion Systems GmbH, where I developed a C position reconstruction system using absolute multiturn encoders.
