About

I'm Jonnie. I work in the Swedish forest industry, where most of my hands-on knowledge lives, and I build software in my own time. I'm self-taught, with no formal background in development, just a genuine pull toward technology and a habit of taking things apart to see how they work.

I like working close to the data, caring about correctness, and making fast things that earn their keep. If it's at the intersection of the forest and good software, I'm probably interested.
