Internet & IT

>10.000 team member

For the Conti ADC500 project:
o Provided several fixes for SD-card booting issues of a Texas Instruments SoC (running Autosar OS, Free RTOS and Linux OS) and RAM layout.
o Created concepts for: booting the SoC via a secondary boot loader; eMMC and Flash partitioning.
o Implemented a proof of concept for booting all SoC’s cores (ARM Cortex-A72, ARM Cortex-R5F, C7x DSP) via the secondary boot loader.
o Implemented Lauterbach scripts for SoC AMP (asymmetrical multiprocessing) debugging and flashing of eMMC/NOR Flash.

Autosar Base SW Architect

Magna Electronics

Internet & IT

>10.000 team member

For the BMW ADCAM project:
o Revised the SW architecture model and verified that all SW requirements were addressed correctly and completely.
o Performed source code reviews on the SOP candidate release.
o Analyzed the safety mechanisms already available in the SOP candidate release SW.
o Identified several critical safety mechanisms in the MCU’s AoUs that were not implemented and provided technical guidance on how to implement.

Senior Embedded SW Engineer

5000-10.000 team member

For the Arene Plane project (a vehicle data logger part of the next generation of autonomous driving SW ecosystem named Arene Platform):
o Integrated a state-of-the art embedded system database engine.
o Improved the CMake build system generator files.
o Provided support on various technical topics (e.g. automotive safety, architecture etc.), performed peer reviews.

Autosar Base SW Architect (Consultant)

Magna Electronics
For the BMW ADCAM project:
o Redesigned and reconfigured OS scheduling, reducing CPU load on core 0 by 16%.
o Created and implemented the memory partitioning concept to address ISO26262's
requirements for freedom from interference.
o Created linker scripts that improved SW runtime and eliminated cache coherency issues.
o Contributed to the safety architecture and its implementation by allocating SW to the
correct memory partitions, introducing mechanisms for temporarily changing the CPU's
privilege mode, configuring the MPU etc.
o Provided technical support to other architects and engineers, especially if the multicore
aspect was involved (e.g. multicore XCP, multipartition BSWM, FiM/Dem master-satellite
concept, multicore EcuM etc.).

Senior Embedded Software Engineer (Consultant)

For the BMW ADCAM project:
o Enabled cores 1 & 2 of the Infineon TC37x MCU, ensuring proper Autosar BSW & RTE
initialization.
o Redeployed SW components to the newly enabled cores, achieving a 20% reduction in
CPU load on core 0.
o CPU load on core 0 was further reduced by an extra 37%, reaching a total load of ~40%,
by updating the linker scripts to use addresses that don't bypass the PCACHE.

Embedded Software Integrator (Consultant)

ThyssenKrupp Components Technology
For the pre-development steer-by-wire EPS system I designed and implemented a:
o Complex ASIL D Autosar SW component that controls current through a solenoid destined
