From a working-class background in rural Germany to the core of global tech infrastructure: Oliver Geiselhardt-Herms (OGH) has little patience for corporate theater or unnecessary protocol layers. Drawing on his experience at DeepL, Cloudflare, EXARING and Google, he bridges the gap between high-level architecture and hands-on execution.

Oliver is a proponent of "Engineering First," focusing on high-throughput L3 fabrics and the elimination of legacy technical debt. This blog serves as a platform for deep dives into Go, BGP, and the grit required to build the networks that power tomorrow’s AI—delivered with a straightforward, no-nonsense attitude.
