About RasmusOS

I'm Rasmus — a software developer, and for the last few years those two words have been in service of a third: freedom. Not the vague kind, but a specific, compounding kind — the freedom to spend part of every year living and working from Japan, and to build a life where a laptop, a mat, and a long time horizon are all I really need.

The developer thread is the engine. I build software professionally and, increasingly, for myself — shipping products and small SaaS experiments on the side, learning the unglamorous parts of running something (pricing, positioning, actually finishing) as much as the code itself. Every project I ship is one more rep toward being able to work from anywhere, on my own terms, which is the whole point.

The aikido thread is where I learned what patience under pressure actually looks like. I trained under the late sensei Shoji Nishio, and the discipline of the mat — showing up, falling, getting back up, refining the same technique for years — turned out to be the same discipline that ships software and holds an investment thesis for a decade. My first trip to Japan wasn't a vacation; it was an international Aikido seminar with eight training partners, and it's the trip that made "living there part of the year" feel less like a daydream and more like a plan with a budget.

The investor thread is the part most people don't see. I started investing at 30, later than I'd have liked, which is exactly why I care about it: long-term, unglamorous, compounding capital toward a concrete goal — a 1M DKK portfolio — is the financial version of the same patience aikido taught me on the mat. It's what turns "I'd like to split my life between Denmark and Japan" from a wish into a number I can actually track.

None of these are side projects to each other. The code funds the trips, the mat teaches the patience the code and the portfolio both need, and the portfolio buys back the time to keep doing all three. This site is where I write that story down as it happens — the wins, the failed experiments, and the slow, compounding progress toward Japan.
