Summary
🤩
Rockstar🎓
Top SchoolSteffen Vogel is a Software Specialist in R&D with 16 years of experience building low-level systems, embedded firmware, and cloud-native tooling from his base in Simmerath, Germany. He blends deep embedded/RT simulation expertise—VHDL, C, assembly and real-time OPAL-RT/RTDS environments—with modern backend and DevOps work in Go, Rust and Kubernetes. Steffen has contributed to notable open-source projects such as JupyterHub’s zero-to-jupyterhub-k8s and kubespawner (improving IPv6 and DNS-based service discovery) and low-level projects like Hermit-OS and PicoRV32, showing a rare full-stack span from unikernels to firmware. His contributions emphasize reliability, maintainability and portability: refactors, improved logging, IPv6 support and cross-platform build improvements recur across his work. He holds an MSc from RWTH Aachen and a track record of research-to-product transitions, from PCIe co-simulation interfaces to production R&D at OPAL-RT. Outside the obvious, Steffen maintains a personal code archive (codeberg.org/stv0g) indicating a disciplined, self-curated body of engineering experiments and tooling.
