Hi, I’m Christian. I develop software for tasks that make me think: there has to be an easier way.
My tools run locally on your computer, require no subscription, and don’t force you into the cloud for every little thing.

I ask myself that question with every new project.
I don’t build a tool just because it is technically possible. There has to be a problem that annoys me, a process that is unnecessarily complicated, or something missing from an existing solution.
Then I start building.
“The software should be easy to understand, perform its core task well, and impose as few restrictions as possible.”
I started developing software long before I made a living from it. I’ve been doing it professionally since 2002—and I still enjoy it just as much today.
ruesken.net is my own thing. It is where I can bring ideas to life that I genuinely enjoy working on. No big software company, no anonymous team, and no made-up startup story.
I develop the applications myself, take care of updates, and answer your messages personally.
