Summary
👤
Senior🎓
Top SchoolPhilipp Ittershagen is a Director of Cloud Architecture & Technologies with 12 years of experience bridging embedded systems research and practical cloud/architecture leadership. He holds a PhD in HW/SW Embedded Systems Design Methodology and has a strong hands-on background in embedded software, C++, SystemC, high-level synthesis and the Clang/LLVM toolchain. At OFFIS he led compiler, virtualization and real-time OS workpackages and supervised teams and student research, and he now drives cloud and architecture strategy at BTC Embedded Systems. His open-source contributions span low-level hypervisor support for ARM (Xvisor) and upstream build-system improvements in Meson, reflecting deep expertise in both system internals and developer tooling. Colleagues rely on him for translating academic rigor into production-grade solutions that integrate embedded constraints with modern cloud architectures. He is based in Oldenburg, Germany, and often combines compiler-level fixes with system-level design to solve non-obvious integration challenges.

Xvisor: eXtensible Versatile hypervISOR
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:9 commits in 9 months
Contributions summary:Philipp's primary contributions involve modifying the Xvisor hypervisor for ARM architecture, specifically focusing on ARM32. They addressed issues in hypercall handling, including fixing argument sizes, adding system mode support, and correcting conditional execution. Furthermore, they added a hypercall for SVC instructions and integrated FreeRTOS guest support for the Cortex-A9. Their work touches on low-level system interactions and guest operating system integration.
