How I work
Quality first
Every line gets senior review, built to enterprise standards. No prototype quality in production — software that lasts for years.
Architecture first
My hours go into design, review and the hard 20% — the part systems stand or fall on. The rest follows from that.
Faster — without compromise
My AI workflow accelerates building, not thinking. That is how I deliver faster — without you seeing it in the quality.

About Casper
I have been programming since I was thirteen and have spent more than ten years building enterprise systems professionally — for years as technical lead of route.nl, then as founding cloud engineer at mosa.cloud, where a small team and I built the platform from scratch.
I believe in software that empowers people and makes an impact: solidly built, clearly explained, no fuss. I work remotely, with a fixed daily rhythm and full focus on one project at a time.
