I build and run the unglamorous stuff that makes the internet work — DNS zones that don't lie, mail that authenticates, servers that stay up, websites that load, uhm and whatever. Then I go argue with an AI agent about why it deleted a file, water something in the garden, and lose my chair to the cat. In that order, most days.

What I actually touch

Not a buzzword cloud — this is the layer stack I get paged for, from copper to checkout page, plus the one layer that isn't strictly my job but is where my head lives lately.

L1–3 · routing Network & Numbers BGP · RIPE NCC · ASN & IPv6 allocation · RPKI · route filtering — the layer where I actually own a piece of the internet, AS207135

L7 · mail Email Infrastructure SPF · DKIM · DMARC · BIMI/VMC · MTA-STS — I've probably explained why your mail lands in spam more times than I'd like to admit

L7 · ops Server & Identity cPanel/WHM · Linux hosting · Microsoft 365 · Entra ID — the pager-duty layer

L7 · apps Web Development PHP · MySQL · HTML/CSS/JS · WordPress — including whatever this site counts as

— · data Spreadsheet Wizardry Advanced Microsoft Access · relational schemas · turning someone's chaos into a form that makes sense

— · obsession Agentic Engineering LLM agents, tool-calling, autonomy loops — the thing I'd be doing even if nobody paid me to. More on that on the about page.

Whatever I feel like writing here

In my this is the one part of it with no structure imposed on it. So this website is propably gonna be your first verion of you even seeing the site... and I hope. The old one was ugly, but it "did its job". Any way. Sun Sept. 20, 2026. A friend of mine asked my if he can "hog" (guys what does hog mean please send me an email explaining ehat that is over at but I am guessing to get) some IPs from my AS207135 so I prepared a document.
