About Me
Digital craftsman, tech junkie, founder of 9yards, and part‑time chaos coordinator (a.k.a. father of four – or at least I like to think I'm coordinating things, but let's be honest, my wife's the one running the actual ops).
I run a tight crew of 8 clever minds in Amsterdam, building webshops that don't just look good, but sell stuff like hell. Been doing this since back when Netscape Navigator was still a thing (yep, I've seen some shit).
By day, I live for clean code, smart UX, and scalable systems. By night, I'm probably soldering something that will never make it past the kitchen table or explaining to my kids for the 17th time what I actually do for a living ("Yes, it's tech. No, I don't fix Wi‑Fi").
Born in Haarlem, now based in the beautiful flatlands of Noord‑Holland, running life from Zuid Scharwoude with my amazing wife and four loveable kids.
I get excited about anything with wires, APIs, or potential for automation – from DIY electronics and smart homes to backend flows and headless commerce. If it connects, I'll probably break it, rebuild it, and then automate it.
Still Dutch, still direct, still curious as hell.
(This text was AI‑generated, because of course it was. We could've written it ourselves… but this was faster, and let's be honest: you get the idea.)
