Hi, this is Johann.

I’m a software engineer with a passion for good design and well‑structured TypeScript 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 – projects that don’t just solve problems but are fun to create and use.
