I’m a Holistic Automation Evangelist, trying to bring software engineering methods to network automation, helping to overcome the vendor lock-in and build solutions that last.

So I will mostly write about network automation, Contemporary Linux networking etc., but might also dive into the worlds of Juniper, Arista, Huawei, Cisco, and the likes. Things like iproute2, ifupdown2/-ng, VXLAN, VRFs, OSPF, BGP, MPLS etc. might come up now and then.

Who am I?

By day I’m working as a Technical Lead SDN at Hetzner Cloud, by night I’m hacking on the infrastructure of the Freifunk Hochstift network (related series, GitHub) and some Open Source projects. The latest notable ones being bio-routing and octopus.

Since the early 2000s I have a heart for Linux and Open Source, developed a weaknes for networking, IPv6 and routing a long while a go and have been a speaker and tutor at the #Routingdays. A while ago I got my hands dirty with ifupdown2, VXLAN, Linux VRFs, infrastructure automation with Salt Stack and “kommunistischen Frickelnetzen” and am afraid of SDNs ever since.

Talks and conferences

I gave a number of talks on various topics around Linux, networking, automation, etc. Most slides can be found on SlideShare, a number of recordings are on media.ccc.de or somewhere on YouTube.

2018 I founded the Network Track at the annual Free and Open Source Software Conference (FrOSCon) and am a member of the PC since.

Lately I happend to become the co-chair of the vNOG meetings. We try to provide a platform for fellow network / infra people to present & exchange ideas around networking, automation, design/architecture of your new cool thing, etc. Want to present something? Please let us know!
