About 01 / 06
“Nothing is as permanent as a temporary solution.”
I'm Marc — an architect and engineer in Copenhagen who's happiest with a genuinely hard problem in front of me. I've been building software for over a decade, and what still pulls me in isn't the technology for its own sake — it's the moment a tangled, high-stakes mess finally clicks into something clean that people can actually trust.
I care about the people as much as the architecture. I like curious, creative people around me, I'd rather share the interesting problems than hoard them, and colleagues will tell you I bring some warmth to a team alongside the strong opinions. Whether it's a national health platform used by millions or Vivian — the legal AI I'm building for Danish lawyers — my measure is always the same: did it make someone's day a little clearer and more dependable?

Architecture enforcement for the age of coding agents — because agents pay for your architecture in tokens. Every boundary becomes a compile-time gate, not a good intention.
