Hello, and welcome! I’m Hagen Paul Pfeifer, Chief Software Strategist based in Munich. I lead company-wide technology strategy, engineering governance, and the standardisation of processes and development practices. I guide the structured adoption of new technologies and large-scale modernisation across engineering domains, translating strategy into robust architectures, tooling, and operating models. My focus is to help large engineering organisations deliver faster and safer with measurable outcomes in quality, performance, and cost, while staying disciplined about maintainability, security, and sustainability.

At the core of my expertise is a deep understanding of software, with particular strengths in operating systems like the Linux kernel, software analysis, security, embedded systems, and network protocols. This deep, integrated grounding is what enables me to design systems that are scalable and efficient.

I’ve contributed to work on TCP, IPv6, and BGPv4 IETF standards - small pieces that helped shape today’s Internet. Upstream, I’ve worked across the Linux kernel: networking, tracing, perf, epoll, and the KVM hypervisor. I’ve also contributed to open-source projects such as tcpdump, gcc, iproute2, libpcap, ns-2 and several others.

Beyond the purely technical, I care about sharing knowledge: I write for Heise Medien, deliver talks, organise conferences, and participate in professional communities such as ACM and the German Informatics Society (Gesellschaft für Informatik e. V.).

Whether you are exploring cutting-edge software solutions or simply interested in the ever-evolving world of technology, I hope you find this space insightful. Welcome to my corner of the digital universe.
