Hi, this is Johann.

I’m a software engineer with a passion for good design and well‑structured architectures.

Eight years ago, I traded my lab coat for a keyboard – and I’ve never looked back. That’s how my calling became my career. The analytical approach I learned as a pharmacist now shapes the way I write code every day.

I learn by building and sharing, which is why I maintain more than two dozen open-source projects on GitHub – from Nuxt modules to TOON, a data format for LLMs. Some have grown into commercial products, like my Kirby plugins.
