About Me

More than writing code.

I'm a web developer based in Vienna, working across frontend development, full-stack applications, and modern web technologies.

Since 2020, I've been building and maintaining web applications with JavaScript, TypeScript, Vue, Nuxt, and Node.js. My experience spans frontend interfaces, API integrations, databases, and the practical challenges of keeping real-world applications running.

What interests me most is not just writing code, but understanding the problem behind it. I enjoy exploring how systems work, finding better solutions, and improving the way software is built.

I'm particularly interested in where web development meets artificial intelligence, from AI-assisted development workflows to the engineering behind AI-powered applications.

This website is where I share my work, the problems I've solved, the things I'm learning, and the direction I'm taking as an engineer.

Currently exploring

Backend engineering, AI engineering, and better ways to build software.

How I work

  • Problem First

    Understanding the problem behind a feature before deciding how to build it.

  • How Systems Work

    Curious about architecture, and about why things behave the way they do.

  • Real-World Reliability

    Maintaining live applications, integrations, and the details that keep them running.

  • AI & Engineering

    AI-assisted workflows, and the engineering behind AI-powered applications.
