About

I've been in IT since the days of the 286 — professionally since 2000, and in SAP since 2006. Long enough to have seen most corners of the stack, and to know there are always more corners.

These days I look after the SAP platform at Würth IT, with teams spread around the globe. Most of my time currently goes into people rather than systems — getting a team ready for a future in the cloud, and planning the move of rather a lot of on-premise systems into SAP RISE. The systems, it turns out, are the easy part.

Somewhere along the way, leading people became the main job: teams across time zones, very different backgrounds, the occasional reorganisation. I treat it like Basis work — keep things running, remove blockers, don't panic. Turns out that works on humans too.

Before that: two decades of planning, building, and running SAP landscapes for companies that rely on them. Mostly, they ran. And before all of it: a 286 in a teenager's room (“for homework”), ISDN channel bonding, the school network, a private IRC network and a bit of webhosting. Uptime mattered even then. Linux came early too — Fedora community, translations, ambassador work. Giving back, quietly.

New topics tend to stick quickly — AI, BTP, people, whatever comes next. Curiosity does most of the work. I post on LinkedIn when it is necessary; most things happen quietly in the background.

Off duty

I serve on the board of the local music and fanfare corps — the only place where I hold root.

Two child processes at home. They use most of the memory, and they cannot be killed. There is also a wife — the one process that deserves far more scheduler time than she gets.

I poke at AI tools to see what they can do — at work and off duty. Once taught an AI class at a primary school. Toughest audience so far; steering committees ask easier questions.
